Candidate Hypervelocity Red Clump Stars in the Galactic Bulge Found Using the VVV and Gaia Surveys
Alonso Luna, Dante Minniti, Javier Alonso-García
We propose a new way to search for hypervelocity stars in the Galactic bulge, by using red clump (RC) giants, that are good distance indicators. The 2nd Gaia Data Release and the n…
Short and long term near-infrared spectroscopic variability of eruptive protostars from VVV
Zhen Guo, P. W. Lucas, C. Contreras Peña +7
Numerous eruptive variable young stellar objects (YSOs), mostly Class I systems, were recently detected by the near-infrared Vista Variables in the Via Lactea (VVV) survey. We pres…
The Southern Photometric Local Universe Survey (S-PLUS): improved SEDs, morphologies and redshifts with 12 optical filters
C. Mendes de Oliveira, T. Ribeiro, W. Schoenell +142
The Southern Photometric Local Universe Survey (S-PLUS) is imaging ~9300 deg^2 of the celestial sphere in twelve optical bands using a dedicated 0.8 m robotic telescope, the T80-So…
Analysis of the physical nature of 22 New VVV Survey Globular Cluster candidates in the Milky Way Bulge
Tali Palma, Dante Minniti, Javier Alonso-García +11
In order to characterize 22 new globular cluster (GC) candidates in the Galactic bulge, we present their colour-magnitude diagrams (CMDs) and Ks-band luminosity functions (LFs) usi…
KMT-2018-BLG-1292: A Super-Jovian Microlens Planet in the Galactic Plane
Yoon-Hyun Ryu, Maria Gabriela Navarro, Andrew Gould +22
We report the discovery of KMT-2018-BLG-1292Lb, a super-Jovian planet orbiting an F or G dwarf , which lies p…
Globular cluster candidates in the Galactic bulge: Gaia and VVV view of the latest discoveries
F. Gran, M. Zoccali, R. Contreras Ramos +7
Thanks to the recent wide-area photometric surveys, the number of star cluster candidates have risen exponentially in the last few years. Most detections, however, are based only o…
