Young Stellar Objects in the Carina nebula: Near-Infrared variability and spectroscopy
Jura Borissova, Radostin Kurtev, Josemanuel Escobar +10
We present a catalog of 652 young stellar objects (YSOs) in the Carina star-forming region. The catalog was constructed by combining near-infrared Ks-band variability from the VIST…
Final Targeting Strategy for the SDSS-IV APOGEE-2S Survey
Felipe A. Santana, Rachael L. Beaton, Kevin R. Covey +43
APOGEE is a high-resolution (R sim 22,000), near-infrared, multi-epoch, spectroscopic survey of the Milky Way. The second generation of the APOGEE project, APOGEE-2, includes an ex…
The G 305 Star-forming Region: II. Irregular variable stars
N. Medina, J. Borissova, R. Kurtev +11
We present a catalog of 167 newly discovered, irregular variables spanning a 7 deg area that encompasses the G 305 star-forming complex, one of the most luminous giant…
Small scale star formation as revealed by VVVX galactic cluster candidates
J. Borissova, R. Kurtev, N. Amarinho +8
We report a search and analysis of obscured cluster candidates in the "VISTA Variables in the Via Lactea eXtended (VVVX)" ESO Public Survey area encompassing the region between 229…
Discovery of a mid-infrared protostellar outburst of exceptional amplitude
P. W. Lucas, J. Elias, S. Points +12
We report the discovery of a mid-infrared outburst in a Young Stellar Object (YSO) with an amplitude close to 8 mag at 4.6 m. WISEA J142238.82-611553.7 is one of 23…
New Galactic Star Clusters Discovered in the Disk Area of the VVVX Survey
J. Borissova, V. D. Ivanov, P. W. Lucas +8
The "VISTA Variables in the Via Lactea eXtended (VVVX)" ESO Public Survey is a near-infrared photometric sky survey that covers nearly 1700 sq. deg towards the Galactic disk and bu…
Long-term Stellar Variability in the Galactic Centre Region
C. Navarro Molina, J. Borissova, M. Catelan +5
We report the detection of variable stars within a 11.5' x 11.5' region near the Galactic centre (GC) that includes the Arches and Quintuplet clusters, as revealed by the VISTA Var…
An Automated tool to detect variable sources in the Vista Variables in the V\'ıa Láctea Survey. The VVV Variables (V) catalog of tiles d001 and d002
Nicolás Medina, Jura Borissova, Amelia Bayo +8
Time-varying phenomena are one of the most substantial sources of astrophysical information and their study has led to many fundamental discoveries in modern astronomy. We have dev…
The Structure of the Young Star Cluster NGC 6231. II. Structure, Formation, and Fate
Michael A. Kuhn, Konstantin V. Getman, Eric D. Feigelson +5
The young cluster NGC 6231 (stellar ages ~2-7 Myr) is observed shortly after star-formation activity has ceased. Using the catalog of 2148 probable cluster members obtained from Ch…
The Structure of the Young Star Cluster NGC 6231. I. Stellar Population
Michael A. Kuhn, Nicolás Medina, Konstantin V. Getman +4
NGC 6231 is a young cluster (age ~2-7 Myr) dominating the Sco OB1 association (distance ~1.59 kpc) with ~100 O and B stars and a large pre-main-sequence stellar population. We comb…
Young Stellar Clusters Containing Massive Young Stellar Objects in the VVV Survey
J. Borissova, S. Ramírez Alegría, J. Alonso +17
The purpose of this research is to study the connection of global properties of eight young stellar clusters projected in the Vista Variables in the Via Lactea (VVV) ESO Large Publ…
Variable Stars in the Quintuplet stellar cluster with the VVV Survey
C. Navarro Molina, J. Borissova, M. Catelan +7
The Quintuplet cluster is one of the most massive star clusters in the Milky Way, situated very close to the Galactic center. We present a new search for variable stars in the vici…
Near-infrared photometry and spectroscopy of the low Galactic latitude globular cluster 2MASS-GC03
Julio A. Carballo-Bello, S. Ramirez Alegria, J. Borissova +12
We present deep near-infrared photometry and spectroscopy of the globular cluster 2MASS-GC03 projected in the Galactic disk using MMIRS on the Clay telescope (Las Campanas Observat…
