The California Legacy Survey V. Chromospheric Activity Cycles in Main Sequence Stars
Howard Isaacson, Andrew W. Howard, Benjamin Fulton +31
We present optical spectroscopy of 710 solar neighborhood stars collected over twenty years to catalog chromospheric activity and search for stellar activity cycles. The California…
Orbital and Atmospheric Characterization of the 1RXS J034231.8+121622 System Using High-Resolution Spectroscopy Confirms That The Companion is a Low-Mass Star
Clarissa R. Do Ó, Ben Sappey, Quinn M. Konopacky +33
The 1RXS J034231.8+121622 system consists of an M dwarf primary and a directly imaged low-mass stellar companion. We use high resolution spectroscopic data from Keck/KPIC to estima…
CD-27 11535: Evidence for a Triple System in the Pictoris Moving Group
Andrew D. Thomas, Eric L. Nielsen, Robert J. De Rosa +20
We present new spatially resolved astrometry and photometry of the CD-27 11535 system, a member of the Pictoris moving group consisting of two resolved K-type stars on a …
VLTI/GRAVITY Observations and Characterization of the Brown Dwarf Companion HD 72946 B
W. O. Balmer, L. Pueyo, T. Stolker +96
Tension remains between the observed and modeled properties of substellar objects, but objects in binary orbits, with known dynamical masses can provide a way forward. HD 72946 B i…
Discovery of a White Dwarf Companion to HD 159062
Lea A. Hirsch, David R. Ciardi, Andrew W. Howard +11
We report on the discovery of a white dwarf companion to the nearby late G dwarf star, HD 159062. The companion is detected in 14 years of precise radial velocity (RV) data, and in…
LACEwING: A New Moving Group Analysis Code
Adric R. Riedel, Sarah C. Blunt, Erini L. Lambrides +3
We present a new nearby young moving group (NYMG) kinematic membership analysis code, LocAting Constituent mEmbers In Nearby Groups (LACEwING), a new Catalog of Suspected Nearby Yo…
