WASP-12b Exhibits Persistent In-Transit H Absorption
Shreyas Vissapragada, Fabienne Nail, Morgan MacLeod +6
High-resolution H and He 10830 Å transit spectroscopy can trace the extended upper atmospheres of exoplanets, typically revealing excess in-transit absorption that occurs in the…
From Discovery to the First Month of the Type II Supernova 2023ixf: High and Variable Mass Loss in the Final Year before Explosion
Daichi Hiramatsu, Daichi Tsuna, Edo Berger +22
We present the discovery of the Type II supernova SN 2023ixf in M101 and follow-up photometric and spectroscopic observations, respectively, in the first month and week of its evol…
Center for Astrophysics Optical Infrared Science Archive. I. FAST Spectrograph
Jessica Mink, Warren R. Brown, Igor V. Chilingarian +6
We announce the public release of 141,531 moderate-dispersion optical spectra of 72,247 objects acquired over the past 25 years with the FAST Spectrograph on the Fred L. Whipple Ob…
Dynamically Tagged Groups of Very Metal-poor Halo Stars from the HK and Hamburg/ESO Surveys
Guilherme Limberg, Silvia Rossi, Timothy C. Beers +13
We analyze the dynamical properties of 1500 very metal-poor (VMP; [Fe/H] ) halo stars, based primarily on medium-resolution spectroscopic data from the HK and…
Mapping the Stellar Halo with the H3 Spectroscopic Survey
Charlie Conroy, Ana Bonaca, Phillip Cargile +8
Modern theories of galaxy formation predict that the Galactic stellar halo was hierarchically assembled from the accretion and disruption of smaller systems. This hierarchical asse…
Medium-resolution Spectroscopy of Red Giant Branch Stars in Centauri
Deokkeun An, Young Sun Lee, Jae In Jung +5
We present [Fe/H] and [Ca/Fe] of red giant branch (RGB) members of the globular cluster Centauri. We collect medium-resolution () spectra using the Blanco…
