Search for Exoplanets around Northern Circumpolar Stars III. Long-Period Radial Velocity Variations in HD 18438 and HD 158996
Lee, Byeong-Cheol; Park, Myeong-Gu; Bang, Tae-Yang +2 more
Detecting exoplanets around giants are useful in understanding the later-stage evolution of planetary systems. We observed the M giant HD 18438 and the K giant HD 158996 as part of a Search for Exoplanets around Northern circumpolar Stars (SENS) and obtained 38 and 24 spectra from 2010 to 2017 using the high-resolution Bohyunsan Observatory Echell…
Infrared Two-Color Diagrams of AGB Stars and Planetary Nebulae Using WISE Data
Suh, Kyung-Won
We present various infrared two-color diagrams (2CDs) using WISE data for asymptotic giant branch (AGB) stars and Planetary Nebulae (PNe) and investigate possible evolutionary tracks. We use the sample of 5036 AGB stars, 660 post-AGB stars, and 2748 PNe in our Galaxy. For each object, we cross-identify the IRAS, AKARI, WISE, and 2MASS counterparts…
Properties of the SCUBA-2 850 µm Sources in the Akari NEP-Deep Field
Goto, Tomotsugu; Kim, Seong Jin; Pearson, Chris +15 more
We carry out the study of SMGs in the AKARI NEP-Deep field using James Clerk Maxwell Telescope (JCMT) SCUBA-2 850 µm source catalog released as a part of SCUBA-2 Cosmology Legacy Survey (S2CLS) program. The SCUBA-2 850 µm map has a root mean square (rms) noise of 1.2 mJy beam^{-1} and covers an area of 0.60 degree^{2}. We find 4 sub-mi…
