2021 occultations and transits of Linus orbiting (22) Kalliope: I. Polygonal and `cliptracing' algorithm
M. Brož, J. Ďurech, M. Ferrais +10
The satellite Linus orbiting the main-belt asteroid (22) Kalliope exhibited occultation and transit events in late 2021. A photometric campaign was organized and observations were…
Another Shipment of Six Short-Period Giant Planets from TESS
Joseph E. Rodriguez, Samuel N. Quinn, Andrew Vanderburg +119
We present the discovery and characterization of six short-period, transiting giant planets from NASA's Transiting Exoplanet Survey Satellite (TESS) -- TOI-1811 (TIC 376524552), TO…
Refinement of the convex shape model and tumbling spin state of (99942) Apophis using the 2020-2021 apparition data
H. -J. Lee, M. -J. Kim, A. Marciniak +30
Context. The close approach of the near-Earth asteroid (99942) Apophis to Earth in 2029 will provide a unique opportunity to examine how the physical properties of the asteroid cou…
A new approach to feature-based asteroid taxonomy in 3D color space: 1. SDSS photometric system
Dong-Goo Roh, Hong-Kyu Moon, Min-Su Shin +1
The taxonomic classification of asteroids has been mostly based on spectroscopic observations with wavelengths spanning from the VIS to the NIR. VIS-NIR spectra of 2500 aster…
Investigation of surface homogeneity of (3200) Phaethon
Hee-Jae Lee, Myung-Jin Kim, Dong-Heun Kim +7
Time-series multi-band photometry and spectrometry were performed in Nov.-Dec. 2017 to investigate the homogeneity of the surface of asteroid (3200) Phaethon. We found that Phaetho…
Reversed radial distribution trend of subpopulations in the globular clusters NGC 362 and NGC 6723
Dongwook Lim, Young-Wook Lee, Mario Pasquato +2
Most globular clusters (GCs) are now known to host multiple stellar populations with different light element abundances. Here we use narrow-band photometry and low-resolution spect…
Low-resolution Spectroscopy for the Globular Clusters with Signs of Supernova Enrichment: M22, NGC 1851 and NGC 288
Dongwook Lim, Sang-Il Han, Young-Wook Lee +5
There is increasing evidence for the presence of multiple red giant branches (RGBs) in the color-magnitude diagrams of massive globular clusters (GCs). In order to investigate the…
Two Distinct Red Giant Branches in the Globular Cluster NGC 288
Dong-Goo Roh, Young-Wook Lee, Seok-Joo Joo +3
We report the presence of two distinct red giant branches (RGBs) in the globular cluster NGC 288 from the narrow-band calcium and Strömgren b & y photometry obtained at the CTIO 4m…
