Stellar and orbital characterization of three low mass M dwarf binary stars with dynamical spectroscopy from the Habitable Zone Planet Finder

Suhani Surana, Chad F. Bender, Caleb I. Cañas +13

Theoretical models of low-mass stars continue to be discrepant with observations when used to examine the mass-radius relationship and other physical parameters of individual stars…

NEIDSpecMatch: stellar parameter estimation with NEID spectra using an empirical library

Te Han, Paul Robertson, Caleb I. Cañas +16

We introduce NEIDSpecMatch, a tool developed to extract stellar parameters from spectra obtained with the NEID spectrograph. NEIDSpecMatch is based on SpecMatch-Emp and HPFSpecMatc…

Multi-Observatory Study of Young Stellar Energetic Flares (MORYSEF): No Evidence For Abnormally Strong Stellar Magnetic Fields After Powerful X-ray Flares

Konstantin V. Getman, Oleg Kochukhov, Joe P. Ninan +9

We explore the empirical power-law relationship between X-ray luminosity (Lx) and total surface magnetic flux (Phi), established across solar magnetic elements, time- and disk-aver…

SPYGLASS. V. Spatially and Temporally Structured Star-Forming Environments in the Cepheus-Hercules Complex

Ronan Kerr, Adam L. Kraus, Daniel Krolikowski +2

Young associations record complete histories of star forming events through their demographics and dynamics, and Gaia has greatly expanded our knowledge of these associations. We p…

The Strength and Variability of the Helium 10830 Å Triplet in Young Stars, with Implications for Exosphere Detection

Daniel M. Krolikowski, Adam L. Kraus, Benjamin M. Tofflemire +3

Young exoplanets trace planetary evolution, particularly the atmospheric mass loss that is most dynamic in youth. However, the high activity level of young stars can mask or mimic…

SPYGLASS. II. The Multi-Generational and Multi-Origin Star Formation History of Cepheus Far North

Ronan Kerr, Adam L. Kraus, Simon J. Murphy +4

Young stellar populations provide a record of past star formation, and by establishing their members' dynamics and ages, it is possible to reconstruct the full history of star form…

TESS Hunt for Young and Maturing Exoplanets (THYME) VII : Membership, rotation, and lithium in the young cluster Group-X and a new young exoplanet

Elisabeth R. Newton, Rayna Rampalli, Adam L. Kraus +36

The public, all-sky surveys Gaia and TESS provide the ability to identify new young associations and determine their ages. These associations enable study of planetary evolution by…

Close companions around young stars

Marina Kounkel, Kevin Covey, Maxwell Moe +26

Multiplicity is a fundamental property that is set early during stellar lifetimes, and it is a stringent probe of the physics of star formation. The distribution of close companion…
