Asteroseismology of massive stars with the TESS mission: the runaway Beta Cep pulsator PHL 346 = HN Aqr

Gerald Handler, Andrzej Pigulski, Jadwiga Daszyńska-Daszkiewicz +21

We report an analysis of the first known Beta Cep pulsator observed by the TESS mission, the runaway star PHL 346 = HN Aqr. The star, previously known as a singly-periodic pulsator…

Diverse Variability of O and B Stars Revealed from 2-minute Cadence Light Curves in Sectors 1 and 2 of the TESS Mission: Selection of an Asteroseismic Sample

May G. Pedersen, Sowgata Chowdhury, Cole Johnston +18

Uncertainties in stellar structure and evolution theory are largest for stars undergoing core convection on the main sequence. A powerful way to calibrate the free parameters used…

The effects of near-core convective shells on the gravity modes of the subdwarf B pulsator KIC 10553698A

Hamed Ghasemi, Ehsan Moravveji, Conny Aerts +2

KIC 10553698A is a hot pulsating subdwarf B (sdB) star observed by the Kepler satellite. It exhibits dipole (l = 1) and quadrupole (l = 2) gravity modes with a clear period spacing…

Asteroseismic Diagnostics for Semi-Convection in B Stars in the Era of K2

Ehsan Moravveji

Semi-convection is a slow mixing process in chemically-inhomogeneous radiative interiors of stars. In massive OB stars, it is important during the main sequence. However, the effic…

Detection of solar-like oscillations in the bright red giant stars Psc and Tau from a 190-day high-precision spectroscopic multisite campaign

P. G. Beck, E. Kambe, M. Hillen +35

Red giants are evolved stars which exhibit solar-like oscillations. Although a multitude of stars have been observed with space telescopes, only a handful of red-giant stars were t…

Echography of young stars reveals their evolution

K. Zwintz, L. Fossati, T. Ryabchikova +17

We demonstrate that a seismic analysis of stars in their earliest evolutionary phases is a powerful method to identify young stars and distinguish their evolutionary states. The ea…
