The first view of δ Scuti and γ Doradus stars with the TESS mission
We present the first asteroseismic results for δ Scuti and γ Doradus stars observed in
Sectors 1 and 2 of the TESS mission. We utilize the 2-min cadence TESS data for a sample …

A Census of B [e] Supergiants
M Kraus - Galaxies, 2019 - mdpi.com
Stellar evolution theory is most uncertain for massive stars. For reliable predictions of the
evolution of massive stars and their final fate, solid constraints on the physical parameters …

An observed population of intermediate-mass helium stars that have been stripped in binaries
The hydrogen-rich outer layers of massive stars can be removed by interactions with a
binary companion. Theoretical models predict that this stripping produces a population of …
