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…
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…
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…
Accurate mass-radius ratios for Hyades white dwarfs
L. Pasquini, A. F. Pala, M. Salaris +4
We use the ESPRESSO spectrograph at the Very Large Telescope to measure velocity shifts and gravitational redshifts of eight bona fide Hyades white dwarfs, with an accuracy better…
Rotation signature of TESS B-type stars. A comprehensive analysis
L. F. Barraza, R. L. Gomes, Y. S. Messias +11
Stellar rotation is a fundamental observable that drives different aspects of stellar and planetary evolution. In this work, we present an unprecedented manifold analysis of 160 B-…
A search for rotation periods in 1000 TESS objects of interest
Bruno L. Canto Martins, Roseane L. Gomes, Yuri S. Messias +8
The high quality light curves from the Transiting Exoplanet Survey Satellite (TESS) represent a unique laboratory for the study of stellar rotation, a fundamental observable drivin…
