TESS Subgiant and Lower Red Giant Asteroseismology in the Continuous Viewing Zones
Sophia Grusnis, Jamie Tayar, Diego Godoy-Rivera
Asteroseismology, the study of stellar oscillations, and stellar modeling both offer profound insights into the fundamental properties and evolution of stars. With pySYD, a new ope…
Beyond the Nyquist frequency: Asteroseismic catalog of undersampled Kepler late subgiants and early red giants
B. Liagre, R. A. García, S. Mathur +9
Subgiants and early red giants are crucial for studying the first dredge-up, a key evolutionary phase where the convective envelope deepens, mixing previously interior-processed ma…
Signature of spin-down stalling in stellar magnetic activity. The case of the open cluster NGC 6811
Ângela R. G. Santos, Diego Godoy-Rivera, Savita Mathur +3
Stellar rotation and magnetic activity have a complex evolution that reveals multiple regimes. One of the related transitions that is seen in the rotation distribution for main-seq…
Magnetic activity evolution of solar-like stars: II. -Ro evolution of Kepler main-sequence targets
Savita Mathur, Angela R. G. Santos, Zachary R. Claytor +16
There is now a large sample of stars observed by the Kepler satellite with measured rotation periods and photometric activity index . We use this data, in conjunction w…
Kepler meets Gaia DR3: homogeneous extinction-corrected color-magnitude diagram and binary classification
D. Godoy-Rivera, S. Mathur, R. A. García +8
The original Kepler mission has delivered unprecedented high-quality photometry. These data have impacted numerous research fields (e.g., asteroseismology and exoplanets), and cont…
Improving the stellar age determination through joint modeling of binarity and asteroseismology -- Grid modeling of the seismic red-giant binary KIC 9163796
D. H. Grossmann, P. G. Beck, S. Mathur +12
Context. Typical uncertainties of ages determined for single star giants from isochrone fitting using single-epoch spectroscopy and photometry without any additional constraints ar…
