The optical photometric variability of Herbig Ae/Be stars from TESS
Ann Marie Cody, Lynne A. Hillenbrand, Shreya Chandragiri +1
We have carried out a photometric time domain study of 188 intermediate-mass young stars observed in Full Frame Image mode with the TESS satellite over the first 3.3 years of its m…
Dynamical Masses for 23 Pre-Main Sequence Stars in Upper Scorpius: A Critical Test of Stellar Evolutionary Models
A. P. M. Towner, J. A. Eisner, P. D. Sheehan +2
We present dynamical masses for 23 pre-main sequence K- and M-type stars in the Upper Scorpius star-forming region. These masses were derived from the Keplerian rotation of CO disk…
Separating Photospheric and Starspot Magnetic Fields in Pre-Main-Sequence Stars Using IGRINS Spectroscopy
Facundo Pérez Paolino, Lynne Hillenbrand, Jeff Bary
Magnetic fields in pre main sequence stars regulate angular momentum evolution, drive magnetic activity, and modify stellar structure, yet their surface distributions remain poorly…
Starspots as an Explanation for the Mysterious IYJ Continuum Excess Emission in Classical T Tauri Stars
Facundo Pérez Paolino, Jeff Bary, Lynne Hillenbrand +2
An accurate estimation of the continuum excess emission from accretion spots and inner circumstellar disk regions is crucial for a proper derivation of fundamental stellar paramete…
SDSS-V Local Volume Mapper (LVM): A Glimpse into Orion
K. Kreckel, O. V. Egorov, E. Egorova +37
The Orion Molecular Cloud complex, one of the nearest (D = 406 pc) and most extensively studied massive star-forming regions, is ideal for constraining the physics of stellar feedb…
