APOKASC-3: The Third Joint Spectroscopic and Asteroseismic catalog for Evolved Stars in the Kepler Fields
Marc H. Pinsonneault, Joel C. Zinn, Jamie Tayar +38
In the third APOKASC catalog, we present data for the complete sample of 15,808 evolved stars with APOGEE spectroscopic parameters and Kepler asteroseismology. We used ten independ…
Abundances of planetary nebulae and evolved stars: Iron and sulfur depletion, and carbon and nitrogen enrichment, in low- and intermediate-mass stellar populations in the Milky Way
Letizia Stanghellini, Verne V. Smith, Katia Cunha +1
We explore the elemental abundances in Galactic planetary nebulae (PNe) compared with those of their stellar progenitors (Red Giant Branch and Asymptotic Giant Branch, RGB and AGB,…
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 a Chromospheric Activity Analysis of a K2 Sample of Planet-Hosting Stars
V. Loaiza-Tacuri, Katia Cunha, Verne V. Smith +4
Effective temperatures, surface gravities, and iron abundances were derived for 109 stars observed by the K2 mission using equivalent width measurements of Fe I and Fe II lines. Ca…
Cool stars in the Galactic Center as seen by APOGEE: M giants, AGB stars and supergiant stars/candidates
M. Schultheis, A. Rojas-Arriagada, K. Cunha +11
The Galactic Center region, including the nuclear disk, has until recently been largely avoided in chemical census studies because of extreme extinction and stellar crowding. Makin…
