Minimizing Star-spot Contamination of Exoplanet Transit Spectroscopy Using Alternate Normalization

The Astronomical Journal
Recently, M. H. Currie et al. (2023) simulated the detection of molecules in the atmospheres of temperate rocky exoplanets transiting nearby M-dwarf stars.

Detailed Analysis of Six Contact Binaries and their Possible Origin

The Astronomical Journal
A photometric investigation of six binary systems of the W Ursae Majoris (W UMa)-type is presented. We extracted primary and secondary minima from the Transiting Exoplanet Survey Satellite observations of these systems.

Mapping of surface activity on the W UMa-type system VW Cephei [PDF]

After multifilter photometry of the W UMa-type contact binary VW Cep (P = 6.67 hr; G5V + K0V) in 1986/87 revealed large asymmetries in the light curves believed to be caused by large, cool starspot regions on the surface of the larger stars, in Apr. 1987

Spot Distribution and Evolution on Two New Active Binaries Discovered in the YNHK Survey

The Astronomical Journal
The study on active binaries can provide detailed insights to understand how binarity affects dynamo actions inside stellar interiors. Here we report two active eclipsing binaries, USNO-B1.0 0743-0306638 and 0763-0282368, discovered in the Yunnan–Hong ...
