Instrument/Telescope used to find: Alfred Jensch
telescope.
Instrument/Telescope used to find: North
Pole region telescope at Bohyunsan
Optical Astronomy
Instrument/telescope used to find:
Applegate’s Mechanism and some
algorithms
No Picture given or found of it….
Which telescope got picture: These are pictures of a
couple different telescopes. It was the only real
picture I could find.
Coordinates: Galactic Longitude:151.35891
Galactic Latitude: 35.95690
Other Fun Info: they were watching the K giant star
Ursae Majoris for three years at the Thuringer
Landessternwarte Tautenburg. They were looking to
understand the nature of the diverse radial velocity
variations in K giant stars. Ended up finding this one
exoplanet revolving around the K star
Telescope that got the picture: 2Mass
Coordinates: Galactic
Longitude:112.79498. Latitude: 39.66113
Other fun Info: They found 200 northern
circumpolar stars to follow around. They
were analyzed and monitored for the past
five years, they found the detection of
four new exoplanets. It has an eccentricity
f 0.19
Coordinates
Lat: 70.27706
Long:104.28613
Other fun info: an eclipsing post-common
envelope binary with a circumbinary disk
and a giant planet. It has angular
momentum losses driven by gravitational
radiation and magnetic braking. However
the observed orbital decay is too fast to
tracked and seen. The circmbinary disk
around DE CV n may be responsible for the
additional angular momentum losses. Its
orbit is a bit off.
