Improved radius determinations for the transiting brown dwarf population in the era of Gaia and TESS
Carmichael, Theron W.
I report updates to the substellar mass-radius diagram for 11 transiting brown dwarfs (BDs) and low-mass stars published before the third data release from the Gaia mission (Gaia DR3). I re-analyse these transiting BD systems whose physical parameters were published between 2008 and 2019 and find that when using the parallax measurements from Gaia…
Testing ultralow amplitude Cepheid candidates in the Galactic disk by TESS and Gaia
Bódi, Attila; Szabó, Róbert; Molnár, László +1 more
Ultralow amplitude (ULA) and strange mode Cepheids are thought to be pulsating variable stars that are near to or are at the edges of the classical instability strip. Until now, a few dozen such variable star candidates have been found both in the Large Magellanic Cloud and the Milky Way. For the present work, we studied six ULA Cepheid candidates…
Modelling simultaneous CoRoT and Spitzer light curves: the impact of bending waves in the inner disc
Nagel, E.; Bouvier, J.
We present a physical interpretation of the amplitude of light curves of young stellar objects (YSOs) simultaneously observed in the infrared with the Spitzer Space Telescope and in the optical with the CoRoT satellite. The modelled objects come from a sample of YSOs in the star forming region NGC 2264, and we focus on a subsample showing periodic…
Frequency analysis of the hybrid δ Sct-γ Dor star CoRoT-102314644
Creevey, O. L.; Pichon, B.; Sánchez Arias, J. P. +1 more
Context. Observations from space missions allowed significant progress due to the absence of atmospheric noise contributions and having uninterrupted data sets. This has been extremely beneficial in asteroseismology because many oscillation frequencies, not observable from the ground, can be detected. One example of this success is the large numbe…
