Relativistic modeling of atmospheric occultations with time transfer functions

A. Bourgoin, M. Zannoni, L. Gomez Casajus +2

Context: Occultation experiments represent unique opportunities for probing remotely physical properties of atmospheres. The data processing requires one to properly account for re…

Debris discs in binaries: morphology and photometric signatures

Philippe Thebault, Quentin Kral, Johan Olofsson

We aim to see whether debris belts evolving in between two stars may be impacted by the presence of the companion and whether this leaves any detectable signature that could be obs…

TESS observations of Cepheid stars: first light results

E. Plachy, A. Pál, A. Bódi +33

We present the first analysis of Cepheid stars observed by the TESS space mission in Sectors 1 to 5. Our sample consists of 25 pulsators: ten fundamental mode, three overtone and t…

The impact of a fossil magnetic field on dipolar mixed-mode frequencies in sub- and red-giant stars

L. Bugnet, V. Prat, S. Mathis +5

Stars more massive than M are known to develop a convective core during the main-sequence: the dynamo process triggered by this convection could be the origin of…
