Picture an Astronomer: Best Practices for Retaining Talent in Astrophysics

Ava Polzin, Katherine E. Whitaker, C. Megan Urry +85

Women are consistently underrepresented in astrophysics yet are simultaneously subject to disproportionate attrition at every career stage. This disparity between demonstrated effi…

Recovering Signals in CoRoT Mission (RSCoRoT): I. Short Period Variable Stars

C. E. Ferreira Lopes, A. Papageorgiou, B. L. Canto Martins +8

The CoRoT (Convection, Rotation, and planetary Transits) mission still holds a large trove of high-quality, underused light curves with excellent signal-to-noise and continuous cov…

NSVS 14256825: period variation and orbital stability analysis of two possible substellar companions

Konstantinos Zervas, Panagiota-Eleftheria Christopoulou

Recent period investigations of the Post-Common Envelop Binary (PCEB) NSVS 14256825 suggested that two circumbinary companions were necessary to explain the observed Eclipse Timing…

A study of nine extreme low mass ratio contact binary systems

E. Lalounta, P. -E. Christopoulou, A. Papageorgiou +2

Low mass ratio systems (LMR) are a very interesting class of contact eclipsing binaries challenging the theoretical models of stability. These systems are also considered possible…

A Unique Low-Mass Ratio Contact Eclipsing Binary System under the Period Cut-Off

A. Papageorgiou, P. -E. Christopoulou, E. Lalounta +5

We present a multi-band photometric analysis of CRTS J163819.6+03485, the first low mass ratio (LMR) contact binary system with a period under the contact binary (CB) period limit.…

Three Ultra-short Period Contact Eclipsing Binary Systems Mined from Massive Astronomical Surveys

A. Papageorgiou, P. -E. Christopoulou, C. E. Ferreira Lopes +3

We present the photometric analysis of three ultra-short period total eclipsing binaries in contact configuration, CRTS_J172718.0+431624, OGLE-BLG-ECL-000104, and OGLE-BLG-ECL-0000…
