Evidence of distant spiral arms in the Galactic disk quadrant IV from VVV red clump giants

R. Kammers, R. K. Saito, E. Botan +4

The discovery of new clear windows in the Galactic plane using the VVV near-IR extinction maps allows the study of the structure of the Milky Way (MW) disk. The ultimate goal of th…

UGPS J194310+183851: an Unusual Optical and X-ray Faint Cataclysmic Variable?

C. Morris, T. J. Maccarone, P. W. Lucas +7

The growing number of multi-epoch optical and infrared sky surveys are uncovering unprecedented numbers of new variable stars, of an increasing number of types. The short interval…

The VVV Open Cluster Project II. Near-infrared sequences of 37 open clusters on eight-dimensional parameter space

K. Peña Ramírez, L. C. Smith, S. Ramírez Alegría +4

Open clusters are key coeval structures that help us understand star formation, stellar evolution and trace the physical properties of our Galaxy. In the past years, the isolation…

Large amplitude periodic outbursts and long period variables in the VVV VIRAC2- database

Zhen Guo, P. W. Lucas, L. C. Smith +13

The VISTA Variables in the Via Lactea (VVV) survey obtained near-infrared photometry toward the Galactic bulge and the southern disc plane for a decade (2010 - 2019). We designed a…

Assessing the stellar population and the environment of an HII region on the far side of the Galaxy

A. -N. Chené, R. A. Benjamin, S. Ramírez Alegría +15

We have investigated the stellar and interstellar content of the distant star formation region IRAS 17591-2228 (WISE HII region GAL 007.47+0.06). It is associated to a water maser,…

Polarization of hot Jupiter systems: a likely detection of stellar activity and a possible detection of planetary polarization

Jeremy Bailey, Kimberly Bott, Daniel V. Cotton +6

We present high-precision linear polarization observations of four bright hot Jupiter systems ( Boo, HD 179949, HD 189733 and 51 Peg) and use the data to search for polarized re…
