NGC 4449
Rating: 3 E
Other Names: UGC 7592, H I 213
Astronomical League Program: Caldwell Club; Herschel 400 Club
Position: 1228+4406
Type: Gal
Surface brightness: 12.8
Class: IBm IV
Dimensions: 4' x 3'
Magnitude: 10.3
PA: 45
Notes:
NGC 4449 was one of William Herschel's discoveries; he found it on April 27, 1788.
NGC 4449 is a Magellanic dwarf galaxy and a member of the nearby Canes
Venaticorum group of galaxies. The morphology and absolute size is remarkebly similar
to our neighbour galaxy LMC (Large Magellanic Cloud). The bar consists of a population
of stars with an age older than five million years.The red regions in the upper northern
part of the image which emit most of their light in the H-alpha line are HII regions with
embedded ongoing star formation. There are several bluish white star clusters visible,
some of them near filaments of dust which provide the fuel for future star formation. In
the western part of the image (right hand side) there is an isolated supergiant shell of Halpha emission which probably is ionized by the central cluster of stars. Radio
observations in the HI line show that NGC 4449 is embedded in a huge gaseous halo with
a diameter of 14 times the optical one.
[Source :http://www.seds.org/~spider/spider/Misc/n4449.html]
Observations:
C8 at 83x. It is uniform, and shows a pronounced brightening at the center (at high
power, where it also takes on a mottled appearance). It has a roughly rectangular shape.
I think the NE end is a little brighter. It lies 10 min SW of a 9m star.
Model (where the Sun is a baseball):
Its diameter would be 5 million miles.

Notes:
Member of the Canes Venatici II Cloud.
It is interacting with NGC 4485, a dim smudge just north. This pair of galaxies often
goes by the nickname of the "Cocoon Galaxy." Each "blob" is actually a spiral galaxy
that has been distorted by the other. Hints of spiral structure are still evident in the
smaller galaxy. These galaxies have already passed their closest approach
(perigalacticon) and are now speeding away from each other. A tail of stars stretches
between the galaxies which are separated by at least 24,000 light years.

This galaxy produced supernova 1982F (type IIp).
Observations:
C8 at 83x. Faint, but with strong nucleus. High powers don't help much. Its axis
runs NW to SE, and it lies 42 min WNW of Beta CVn. Another faint star lies 7 min S.

Notes:
This is a Type I Seyfert galaxy that is also emitting X-rays and radio waves.
Seyfert galaxies are named for their discoverer, Carl Seyfert, who detected them in
1943. Over 150 are presently known, all rather nearby.
Most of their output is in the infra-red, with some X-rays and ultra-violet. They are
variable (on a timescale of months) and are only 1% as powerful as quasars (but still
several times more powerful than an average galaxy). About 1% of all spiral galaxies (or
10% of all giant spirals) may be Seyferts.
Their power mechanism seems to lie in ionized gas that surrounds the galactic
nucleus, giving rise to strong emission lines. There are two types, which differ only in
their spectral line signatures. Type I show broad Balmer hydrogen lines and narrow lines
- 23 -

of ionized metals (similar to a quasar's broad and narrow line regions). Type II show the
narrow lines only. The difference is due to the galaxy's inclination to us— Type I's tend
to be face-on, while Type II's tend to be edge-on.
Observations:
C8 at 104x. It shows a stellar nucleus (or a foreground star on the line of sight) with
very faint halo, in a faint triangle of stars.

Star A is a spectroscopic binary with a period of 6.65 years. It is also an infra-red
source.
It is the prototypical Beta CVn variable.
From James Kaler's Star Notes:
"Chara" is from Greek meaning "joy." Chara's most interesting aspect is its similarity
to the Sun. The principal component of Alpha Centauri, the third brightest star in the sky,
is also similar, but it has a bright companion. Chara, on the other hand, like the Sun,
seems to be single. The majority of bright naked eye stars are considerably more
luminous than the Sun, some vastly so, a natural result of their intrinsic brilliance, such
stars visible over great distances. However, our Sun, a modest star in the middle of the
full range of stellar brightness, would be invisible to the eye if only 70 light years away.
At a distance of 27 light years, Chara provides a good chance to see what the Sun would
look like at stellar distances.
It is a warm class G star with a temperature of 5,860 Kelvin (only 80 degrees hotter
than the Sun), a mass only four percent smaller, and a radius but four percent larger,
though it is 25 percent more luminous. Since main sequence hydrogen-fusing stars
brighten and swell somewhat as they age, Chara may be one or two billion years older
than the Sun. Chara is also detected in the X-ray part of the spectrum, implying that it too
has a surrounding hot corona, as expected. Extending the solar similarity, Chara even
rotates at a similar speed. The biggest difference, other than luminosity, seems to be a
metal content less than solar, the star having only about 60 percent as much iron. So if
you want to see the Sun from afar, take a look at Canes Venatici's "southern dog." Could
Chara have planets too? We do not know, and for now is not on observing lists that will
check the possibility. If it does, our Sun would look almost the same from there as Chara
does to us.

Observations:
C11 at 115x. B is too close for small instruments.
The AC measures look very unusual. A check of the Digitized Sky Survey (DSS2)
plate of 1950.37 shows a measure of 256.2" @ 210.7. This appears to be a very high
proper motion star system. The PM of A is -705, +293, while that of C is -5, -8 (all mas
per year). The rapid changes can be explained by the proper motion.

It is 33,000 light years in diameter and is a Seyfert galaxy.
Observations:

better view of the nucleus but doesn't help with anything else. It has an E-W axis and lies

Notes:
1822: 19.9 @ 225. 96 measurements. Both stars are spectroscopic binaries. They
are probably about 770 AU apart. The stars share a large common proper motion.
The primary is the prototype of the Alpha CVn variables. These stars have variable
magnetic spectra-- that is, there are periodic changes in some of the metallic lines in the
star's spectrum. In Alpha CVn's case, the period is 5.46939 days, and the chemical and
physical changes in the star change its luminance by about 0.05 magnitudes.
It is popularly believed to be named for King Charles, king of England, by Edmund
Halley (because it supposedly shone with extra splendor on the night of May 29, 1660,
- 33 -
Zone 94
the eve of Charles's return to England), but actually it was named for the executed
Charles I, the star's full name being Cor Caroli Regis Martyris.
It is rich in silicon, europium and mercury, and is a member of the Hyades group. It
is 4.1 times larger than the Sun and is the prototype Alpha CVn variable. It is also an
infra-red source.
From James Kaler's Star Notes:
Cor Caroli is the brightest star of the modern constellation Canes Venatici, the
Hunting Dogs, invented in the 17th century by the astronomer Hevelius to help fill in the
blanks left over by the ancients. It is a white star with a surface temperature of 9,500
Kelvin, about double that of the Sun. It is relatively faint compared with others of its
class.
Much more interestingly, Cor Caroli (Alpha-2) is a "magnetic star," and possesses one
of the strongest known magnetic fields among otherwise normal "main sequence" stars,
youthful unevolved stars like the Sun. The Sun has an overall magnetic field that is only a
few time stronger than Earth's; Cor Caroli's, on the other hand, has one 1500 times
stronger. The star also has a weird chemical composition in which elements such as
silicon, mercury, and rarer elements such as europium are locally enormously enhanced.
Astronomers think the magnetic field is responsible for helping to redistribute the
elements in the star's atmosphere, apparently enriching some, depleting others.
Observations:
C8 at 65x. This is one of the finest doubles in the sky!
