Carbon in J0815+4729: Casting a shadow of doubt on the interpretation of CH absorption in the most primitive stars
Junbo Zhang, Carlos Allende Prieto, Yeisson Osorio +7
Aims. We revisit the carbon abundance in the primitive iron-poor star J0815+4729 ([Fe/H] = -5.49). J0815+4729 is so carbon-enhanced and oxygen-rich that, in addition to CH and C2 m…
The WEAVE-TwiLight-Survey: Expanding WEAVE's Reach to Bright and Low-Surface-Density Targets with a Novel Observing Mode
Thomas Hajnik, Nicholas A. Walton, Giuseppe D'Ago +28
Current-day multi-object spectroscopic surveys are often limited in their ability to observe bright stars due to their low surface densities, resulting in increased observational o…
An Analysis of the Radius Gap in a Sample of Kepler, K2 and TESS exoplanets orbiting M Dwarf Stars
Fábio Wanderley, Katia Cunha, Verne V. Smith +11
Planetary radii are derived for 218 exoplanets orbiting 161 M dwarf stars. Stellar radii are based on an analysis of APOGEE high-resolution near-IR spectra for a subsample of the M…
Stellar Atmospheres
Joachim Puls, Artemio Herrero, Carlos Allende Prieto
Stars play a decisive role in our Universe, from its beginning throughout its complete evolution. For a thorough understanding of their properties, evolution, and physics of their…
Four New Massive Pulsating White Dwarfs Including an Ultramassive DAV
Brandon Curd, A. Gianninas, Keaton J. Bell +5
We report the discovery of four massive () ZZ Ceti white dwarfs, including an ultramassive star. We obtained ground based, time-series photometry…
Chemical tagging with APOGEE: Discovery of a large population of N-rich stars in the inner Galaxy
Ricardo P. Schiavon, Olga Zamora, Ricardo Carrera +42
Formation of globular clusters (GCs), the Galactic bulge, or galaxy bulges in general, are important unsolved problems in Galactic astronomy. Homogeneous infrared observations of l…
