Revealing the Field Sub-subgiant Population Using a Catalog of Active Giant Stars and Gaia EDR3
Emily M. Leiner, Aaron M. Geller, Michael A. Gully-Santiago +2
Sub-subgiant stars (SSGs) fall below the subgiant branch and/or red of the giant branch in open and globular clusters, an area of the color-magnitude diagram (CMD) not populated by…
Revised Stellar Parameters for V471 Tau, A Post-common Envelope Binary in the Hyades
Philip S. Muirhead, Jason Nordhaus, Maria R. Drout
V471 Tau is a post-common-envelope binary consisting of an eclipsing DA white dwarf and a K-type main-sequence star in the Hyades star cluster. We analyzed publicly available photo…
Observationally Constraining the Starspot Properties of Magnetically Active M67 Sub-Subgiant S1063
Natalie M. Gosnell, Michael A. Gully-Santiago, Emily M. Leiner +1
Our understanding of the impact of magnetic activity on stellar evolution continues to unfold. This impact is seen in sub-subgiant stars, defined to be stars that sit below the sub…
Progenitor and Close-In Circumstellar Medium of Type II Supernova 2020fqv from High-Cadence Photometry and Ultra-Rapid UV Spectroscopy
Samaporn Tinyanont, Ryan Ridden-Harper, Ryan Foley +35
We present observations of SN 2020fqv, a Virgo-cluster Type II core-collapse supernova (CCSN) with a high temporal resolution light curve from the Transiting Exoplanet Survey Satel…
Stellar convective penetration: parameterized theory and dynamical simulations
Evan H. Anders, Adam S. Jermyn, Daniel Lecoanet +1
Most stars host convection zones in which heat is transported directly by fluid motion, but the behavior of convective boundaries is not well understood. Here we present 3D numeric…
Rossby numbers and stiffness values inferred from gravity-mode asteroseismology of rotating F- and B-type dwarfs: consequences for mixing, transport, magnetism, and convective penetration
C. Aerts, K. Augustson, S. Mathis +5
Multi-dimensional (magneto-)hydrodynamical simulations of physical processes in stellar interiors depend on a multitude of uncalibrated free parameters, which set the spatial and t…
