Exoplanets in the Antarctic Sky. V. The Second Data Release of AST3-II/CHESPA and Newly Found Variables within the Southern Continuous Viewing Zone of TESS

The Astrophysical Journal Supplement Series
Located at Dome A, the highest point on the Antarctic plateau, China’s Kunlun station is a premier ground-based photometric observatory. Its cold, dry, and stable atmosphere allows continuous observation for over 40 days during polar winter, ideal for ...

Discoveries and Properties of EL CVn–type Binaries in the TESS Survey

The Astrophysical Journal
EL CVn–type systems represent a rare evolutionary stage in binary star evolution, providing ideal laboratories for investigating stable mass-transfer processes and the formation of extremely low-mass white dwarfs (ELM WDs).

Inferring Stellar Parameters from Iodine-imprinted Keck/HIRES Spectra with Machine Learning

The Astrophysical Journal Letters
The properties of exoplanet host stars are traditionally characterized through a detailed forward-modeling analysis of high-resolution spectra. However, many exoplanet radial velocity surveys employ iodine-cell-calibrated spectrographs, such that the ...
