Classification of Periodic Variable Stars from TESS

open access: yesThe Astrophysical Journal Supplement Series
The number of known periodic variable stars has increased rapidly in recent years. As an all-sky transit survey, the Transiting Exoplanet Survey Satellite (TESS) plays an important role in detecting low-amplitude variable stars.

IS POLARIS LEAVING THE CEPHEID INSTABILITY STRIP?

open access: yesOdessa Astronomical Publications, 2017
Although Polaris is generally regarded as an overtone pulsator that may soon switch to pulsation in the fundamental mode, it is argued that the variable is actually crossing the instability strip for the first time and is in the process of leaving the ...

The Orbit and Mass of the Cepheid AW Per

open access: yesThe Astrophysical Journal
The Cepheid AW Per is a component in a multiple system with a long-period orbit. The radial velocities of Griffin cover the 38 yr orbit well. An extensive program of interferometry with the Center for High Angular Resolution Astronomy array is reported ...

Gaia DR3 Open Cluster Cepheids: A Unified Catalog with Calibrated Period–Age and Period–Wesenheit Relations

open access: yesThe Astronomical Journal
Classical Cepheids (CCs) in Galactic open clusters (OCs) provide essential observational constraints for calibrating the period–age relation (PAR) and the period–Wesenheit relation (PWR) of CCs. However, distant and long-period OC Cepheids remain limited,
