SDSS-V Local Volume Mapper (LVM): Revealing the Structure of the Rosette Nebula
Mónica A. Villa-Durango, Jorge Barrera-Ballesteros, Carlos G. Román-Zúñiga +19
The Rosette Nebula is a well-known H II region shaped by the interaction of gas with the OB stars of the NGC 2244 stellar association. Located within the remnant of a giant molecul…
Protoplanetary Disk Survival Time-scales: A Blind Survey of Young Clusters up to 100 Myr in the Solar Vicinity
Gregory Mathews Ben, Jessy Jose, Jesús Hernández
We study the protoplanetary disk lifetimes using a large sample of young stellar objects in nearby clusters. To investigate the final phase of disk dissipation, we selected 32 clus…
Testing the bloated star hypothesis in the massive young stellar object IRAS 19520+2759 through optical and infrared variability
Rakesh Pandey, Aina Palau, Javier Serna +8
Using optical time series with Telescopi Joan Oró (TJO), Gaia, TESS, and NEOWISE archival data, we performed a variability study on the candidate bloated massive young stellar obj…
tonalli: an asexual genetic code to characterise APOGEE-2 stellar spectra. I. Validation with synthetic and solar spectra
LucÃa Adame, Carlos Román-Zúñiga, Jesús Hernández +2
We present tonalli, a spectroscopic analysis python code that efficiently predicts effective temperature, stellar surface gravity, metallicity, -element abundance, and rotation…
Kinematic study of the Orion Complex: Analysing the young stellar clusters from big and small structures
Sergio Sánchez-Sanjuán, Jesús Hernández, Ãngeles Pérez-Villegas +4
In this work, we analysed young stellar clusters with spatial and kinematic coherence in the Orion star-forming complex. For this study, we selected a sample of pre-main sequence c…
