VVV-WIT-07: another Boyajian's star or a Mamajek's object?
Roberto K. Saito, Dante Minniti, Valentin D. Ivanov +6
We report the discovery of VVV-WIT-07, an unique and intriguing variable source presenting a sequence of recurrent dips with a likely deep eclipse in July 2012. The object was foun…
VVV Survey of Blue Horizontal-Branch Stars in the Bulge-Halo Transition Region of the Milky Way
Katherine Montenegro, Dante Minniti, Javier Alonso-García +4
We characterize the population of blue horizontal-branch (BHB) stars in the bulge-halo transition region of the Milky Way using the VISTA Variables in the Vía Láctea (VVV) ESO Publ…
The structure behind the Galactic bar traced by red clump stars in the VVV survey
Oscar A. Gonzalez, Dante Minniti, Elena Valenti +8
Red clump stars are commonly used to map the reddening and morphology of the inner regions of the Milky Way. We use the new photometric catalogues of the VISTA Variables in the Vía…
Milky Way demographics with the VVV survey. IV. PSF photometry from almost one billion stars in the Galactic bulge and adjacent southern disk
Javier Alonso-García, Roberto K. Saito, Maren Hempel +10
The inner regions of the Galaxy are severely affected by extinction, which limits our capability to study the stellar populations present there. The Vista Variables in the Via Lact…
A new near-IR window of low extinction in the Galactic plane
Dante Minniti, Roberto K. Saito, Oscar A. Gonzalez +8
The windows of low extinction in the Milky Way (MW) plane are rare but important because they enable us to place structural constraints on the opposite side of the Galaxy, which ha…
