Starspots and Undetected Binary Stars Have Distinct Signatures in Young Stellar Associations

open access: yesThe Astrophysical Journal
Young stars form in associations, meaning that young stellar associations provide an ideal environment to measure the age of a nominally coeval population.

The Baryonic Tully–Fisher Relation. II. Stellar Mass Models

open access: yesThe Astronomical Journal
We present new color–ϒ _* (mass-to-light ratio) models to convert Wide-field Infrared Survey Explorer W1 fluxes into stellar masses. We outline a range of possible star formation histories and chemical evolution scenarios to explore the confidence limits

Effects of Galactic Environment on Size and Dark Matter Content in Low-mass Galaxies

open access: yesThe Astrophysical Journal
We utilize the cosmological volume simulation FIREbox to investigate how a galaxy’s environment influences its size and dark matter content. Our study focuses on approximately 1200 galaxies (886 central and 332 satellite halos) in the low-mass regime ...

Simulated Coronal Mass Ejections on a Young Solar-type Star and the Associated Instantaneous Angular Momentum Loss

open access: yesThe Astrophysical Journal
Coronal mass ejections (CMEs) on stars can change the stars’ magnetic field configurations and mass-loss rates during the eruption and propagation and therefore, may affect the stars’ rotation properties on long timescales.
