Frequencies analysis of the hybrid delta Sct-gamma Dor star CoRoT-102314644 Open
Observations from space missions have allowed significant progress in many scientific domains due to the absence of atmospheric noise contributions and having uninterrupted data sets. In the context of asteroseismology, this has been extre…

Frequency analysis of the hybrid <i>δ</i> Sct-<i>γ</i> Dor star CoRoT-102314644 Open
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 oscillatio…

Four winters of photometry with ASTEP South at Dome C, Antarctica Open
Context . Dome C in Antarctica is a promising site for photometric observations thanks to the continuous night during the Antarctic winter and favorable weather conditions. Aims .We developed instruments to assess the quality of this site …

HYDRODYNAMIC MODEL FOR A β Cephei VARIABLE BW Vulpeculae Open
A hydrodynamical model for the high-amplitude β Cephei star BW Vulpeculae is generated, and the spectral line profiles are calculated for different pulsational phases. The pulsational characteristics and line profiles are compared with rec…

A CATALOG OF ECLIPSING BINARIES AND VARIABLE STARS OBSERVED WITH ASTEP 400 FROM DOME C, ANTARCTICA Open
We used the large photometric database of the ASTEP program, whose primary goal was to detect exoplanets in the southern hemisphere from Antarctica, to search for eclipsing binaries (EcBs) and variable stars. 673 EcBs and 1166 variable sta…
