Open Clusters as Laboratories for Cool Star Evolution: Highlights from the Cool Stars 23 Splinter Session
Deepak Chahal, Beatrice Caccherano, Edward Gillen +16
Open clusters remain among the most powerful laboratories for calibrating how fundamental stellar properties such as rotation, magnetic activity, surface chemistry, and internal st…
Chemical Abundances of M and G Dwarfs in the Hyades and Coma Berenices Open Clusters from APOGEE Spectra
Deusalete Vilar, Diogo Souto, Katia Cunha +8
Open clusters are one of the best astrophysical laboratories we have available for stellar astrophysics studies. This work presents metallicities and individual abundances for four…
Metallicities of M Dwarf Planet Host Stars from Kepler, K2, and TESS observed by APOGEE: Trends with Exoplanetary Radii and Orbital Periods
Fábio Wanderley, Katia Cunha, Diogo Souto +2
One important property in studying the exoplanet population is the host star metallicity ([M/H]). In this study, we derived stellar metallicities and oxygen abundances for 48 M dwa…
Chemical Abundances for a Sample of FGK dwarfs in the Pleiades Open Cluster from APOGEE
Vinicius Grilo, Diogo Souto, Katia Cunha +8
This paper presents chemical abundances of twelve elements (C, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, and Fe) for 80 FGK dwarfs in the Pleiades open cluster, which span a temperatur…
Magnetic Fields in a sample of planet-hosting M dwarf stars from Kepler, K2, and TESS observed by APOGEE
Fábio Wanderley, Katia Cunha, Verne Smith +8
Stellar magnetic fields have a major impact on space weather around exoplanets orbiting low-mass stars. From an analysis of Zeeman-broadened Fe I lines measured in near-infrared SD…
Magnetic Fields of M Dwarfs from the Pleiades Open Cluster
Fabio Wanderley, Katia Cunha, Oleg Kochukhov +10
Average magnetic field measurements are presented for 62 M-dwarf members of the Pleiades open cluster, derived from Zeeman-enhanced Fe I lines in the H-band. An MCMC methodology wa…
Stellar Characterization and Chemical Abundances of Exoplanet Hosting M dwarfs from APOGEE Spectra: Future JWST Targets
Edypo Melo, Diogo Souto, Katia Cunha +11
Exoplanets hosting M dwarfs are the best targets to characterize Earth-like or super-Earth planetary atmospheres with the James Webb Space Telescope (JWST). We determine detailed s…
Stellar Characterization and Radius Inflation of Hyades M Dwarf Stars From the APOGEE Survey
Fábio Wanderley, Katia Cunha, Diogo Souto +23
We present a spectroscopic analysis of a sample of 48 M dwarf stars () from the Hyades open cluster using high-resolution H-band spectra from the…
Stellar Characterization of M-dwarfs from the APOGEE Survey: A Calibrator Sample for the M-dwarf Metallicities
Diogo Souto, Katia Cunha, Verne V. Smith +18
We present spectroscopic determinations of the effective temperatures, surface gravities and metallicities for 21 M-dwarfs observed at high-resolution (R 22,500) in the \tex…
