Atmospheric parameters and chemical abundances of young stars with APOGEE. I. Orion star-forming region
Ricardo López-Valdivia, LucÃa Adame, Carlos G. Román-Zúñiga +19
We derive atmospheric parameters and chemical abundances in young G-, K-, and M-type stars (temperatures between 6500 and 3100 K) using infrared APOGEE-2 spectra. Atmospheric param…
Fibrations on Handlebodies
Jesús Hernández Hernández, Christopher J. Leininger, Ferrán Valdez
We show that the open genus 2 handlebody admits uncountably-many fibrations over the circle with fiber homeomorphic to the Cantor tree surface with non-conjugate monodromies in the…
The ODYSSEUS Survey. Characterizing magnetospheric geometries and hotspot structures in T Tauri stars
Caeley V. Pittman, C. C. Espaillat, Connor E. Robinson +20
Magnetospheric accretion is a key process that shapes the inner disks of T Tauri stars, controlling mass and angular momentum evolution. It produces strong ultraviolet and optical…
A New Look at Disk Winds and External Photoevaporation in the -Orionis Cluster
K. Maucó, C. F. Manara, A. Bayo +12
Disk winds play a crucial role in the evolution of protoplanetary disks. Typical conditions for star and planet formation are in regions with intermediate or strong UV radiation fi…
