Asteroseismology and interferometry of the F7V spectroscopic binary Draconis A in the TESS CVZ
Jonatan Rudrasingam, Mikkel N. Lund, Frank Grundahl +26
We present a detailed analysis of the asteroseismic main-sequence benchmark star Dra A in the TESS northern CVZ. We aim to derive stellar mass and radius from asteroseismic mod…
Hints of enhanced magnetic activity after the intermediate rotation period gap as traced by the chromospheric Ca ii infrared triplet
Diego Godoy-Rivera, Savita Mathur, Tyler Richey-Yowell +5
For low-mass stars (M < 1.4 Msun), the connection between stellar rotation and magnetic activity governs stellar spin-down, shapes the environments of their exoplanets, and provide…
Characterizing six seismic solar analogs observed by Kepler, K2, and HERMES
R. A. García, S. Mathur, G. T. Hookway +31
Solar analogs, stars that closely match the fundamental properties of the Sun, provide key benchmarks for testing stellar structure and evolution across different ages and activity…
Mining the Kepler Field: Atmospheric Parameters, Bolometric Corrections, and Luminosities
Diego Godoy-Rivera, Desmond H. Grossmann, Tyler Richey-Yowell +3
The ~ 200,000 stars observed by the Kepler mission have provided unprecedented constraints across astrophysics. With the advent of modern spectroscopic and photometric surveys, new…
Dynamical mass of a solar-like oscillator at the main-sequence turnoff from Gaia astrometry & ground-based spectroscopy
P. G. Beck, T. Masseron, K. Pavlovski +11
Asteroseismology is widely used for precise determining of masses of solar-like oscillating stars by performing individual-frequency modeling or applying homological scaling relati…
Testing Red Clump Models with the Asteroseismic Binary KIC 10841730
Lea S. Schimak, Timothy R. Bedding, Courtney L. Crawford +9
Binaries in which both stars are pulsating are rare but extremely valuable. We present the first study of an asteroseismic binary system consisting of a core helium-burning red clu…
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…
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…
Constraining stellar and orbital co-evolution through ensemble seismology of solar-like oscillators in binary systems -- A census of oscillating red-giants and main-sequence stars in Gaia DR3 binaries
P. G. Beck, D. H. Grossmann, L. Steinwender +23
Binary systems constitute a valuable astrophysics tool for testing our understanding of stellar structure and evolution. Systems containing a oscillating component are interesting…
The BRITE-SONG of Aldebaran -- Stellar Music in three voices
P. G. Beck, R. Kuschnig, G. Houdek +20
Solar-like oscillations in red-giant stars are now commonly detected in thousands of stars with space telescopes such as the NASA Kepler mission. Parallel radial velocity and photo…
