A portrait of the rotation of Ultra-Cool Dwarfs revealed by TESS
D. O. Fontinele, P. D. S. de Lima, Y. S. Messias +7
This study presents the results of a search for rotation signature in 250 Gaia DR3 Ultra-Cool Dwarfs (UCDs) with TESS light curves. We identified 71 targets with unambiguous period…
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…
Pulsation in TESS Objects of Interest
R. L. Gomes, B. L. Canto Martins, D. O. Fontinele +11
We report the discovery of three Transiting Exoplanet Survey Satellite Objects of Interest (TOI) with signatures of pulsation, observed in more than one sector. Our main goal is to…
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.…
Automated classification of eclipsing binary systems in the VVV Survey
I. V. Daza-Perilla, L. V. Gramajo, M. Lares +4
With the advent of large-scale photometric surveys of the sky, modern science witnesses the dawn of big data astronomy, where automatic handling and discovery are paramount. In thi…
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…
