Five young Scuti stars in the Pleiades seen with Kepler/K2

Simon J. Murphy, Timothy R. Bedding, Timothy R. White +4

We perform mode identification for five Scuti stars in the Pleiades star cluster, using custom light curves from K2 photometry. By creating échelle diagrams, we identify radial…

The BAyesian STellar Algorithm (BASTA): a fitting tool for stellar studies, asteroseismology, exoplanets, and Galactic archaeology

V. Aguirre Børsen-Koch, J. L. Rørsted, A. B. Justesen +16

We introduce the public version of the BAyesian STellar Algorithm (BASTA), an open-source code written in {\tt Python} to determine stellar properties based on a set of astrophysic…

A 20-Second Cadence View of Solar-Type Stars and Their Planets with TESS: Asteroseismology of Solar Analogs and a Re-characterization of pi Men c

Daniel Huber, Timothy R. White, Travis S. Metcalfe +50

We present an analysis of the first 20-second cadence light curves obtained by the TESS space telescope during its extended mission. We find a precision improvement of 20-second da…

Asteroseismology of iota Draconis and Discovery of an Additional Long-Period Companion

Michelle L. Hill, Stephen R. Kane, Tiago L. Campante +25

Giant stars as known exoplanet hosts are relatively rare due to the potential challenges in acquiring precision radial velocities and the small predicted transit depths. However, t…

TESS Data for Asteroseismology: Photometry

Rasmus Handberg, Mikkel N. Lund, Timothy R. White +12

Over the last two decades, asteroseismology has increasingly proven to be the observational tool of choice for the study of stellar physics, aided by the high quality of data avail…

Characterization of the variability in the O+B eclipsing binary HD 165246

Cole Johnston, Nicolas Aimar, Michael Abdul-Masih +8

O-stars are known to experience a wide range of variability mechanisms originating at both their surface and their near-core regions. Characterization and understanding of this var…
