Two young eclipsing binaries in Orion with temperatures and radii affected by spots and third bodies
Marina Kounkel, Keivan G. Stassun
In this work we present a model of two young eclipsing binaries in the Orion Complex. Both heavily spotted, they present radii and temperatures that are in disagreement with the pr…
Atmospheric parameters and chemical abundances within 100 pc. A sample of G, K, and M main-sequence stars
Ricardo López-Valdivia, Lucía Adame, Eduardo Zagala Lagunas +9
To date, we have access to enormous inventories of stellar spectra that allow the extraction of atmospheric parameters and chemical abundances essential in stellar studies. However…
The TEMPO Survey II: Science Cases Leveraged from a Proposed 30-Day Time Domain Survey of the Orion Nebula with the Nancy Grace Roman Space Telescope
Melinda Soares-Furtado, Mary Anne Limbach, Andrew Vanderburg +26
The TEMPO (Transiting Exosatellites, Moons, and Planets in Orion) Survey is a proposed 30-day observational campaign using the Nancy Grace Roman Space Telescope. By providing deep,…
The evolution of stellar X-ray activity and angular momentum as seen by eROSITA, TESS, and Gaia
Keivan G. Stassun, Marina Kounkel
We have assembled a sample of 8200 stars with spectral types F5V-M5V, all having directly measured X-ray luminosities from eROSITA and rotation periods from TESS, and having…
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…
Protostellar spin-up and fast rotator formation through binary star formation
Rajika L. Kuruwita, Christoph Federrath, Marina Kounkel
(Edited) Many fast rotator stars (rotation periods of < 2 days) are found in unresolved binaries with separations of tens of au. This correlation leads to the question of whether t…
