PBjam: A Python package for automating asteroseismology of solar-like oscillators
M. B. Nielsen, G. R. Davies, W. H. Ball +14
Asteroseismology is an exceptional tool for studying stars by using the properties of observed modes of oscillation. So far the process of performing an asteroseismic analysis of a…
Towards the true number of flaring giant stars in the Kepler field. Are there flaring specialities associated with the giant nature?
K. Oláh, Zs. Kővári, M. N. Günther +4
We aim to give a reliable estimate of the number of flaring giant stars in the Kepler field. By analyzing the flaring activity of these stars we explore their flare statistics and…
Data Analysis of Bright Main-Sequence A- and B-type Stars Observed Using the TESS and BRITE Spacecraft
Joyce A. Guzik, Jason Jackiewicz, Andrzej Pigulski +5
During the last two years we have received long time-series photometric observations of bright (V mag < 8) main-sequence A- and B-type stars observed by the NASA TESS spacecraft an…
The Evolution of Rotation and Magnetic Activity in 94 Aqr Aa from Asteroseismology with TESS
Travis S. Metcalfe, Jennifer L. van Saders, Sarbani Basu +29
Most previous efforts to calibrate how rotation and magnetic activity depend on stellar age and mass have relied on observations of clusters, where isochrones from stellar evolutio…
Active red giants: close binaries versus single rapid rotators
Patrick Gaulme, Jason Jackiewicz, Federico Spada +7
The objective of this work is to determine what fraction of red-giant (RG) stars shows photometric rotational modulation, and understand its origin. One of the underlying questions…
Investigating surface correction relations for RGB stars
Andreas Christ Sølvsten Jørgensen, Josefina Montalbán, Andrea Miglio +7
State-of-the-art stellar structure and evolution codes fail to adequately describe turbulent convection. For stars with convective envelopes, such as red giants, this leads to an i…
