Photometric [Fe/H] of RRab stars in the and bands by deep learning

István Dékány, Eva K. Grebel

RR Lyrae stars are useful chemical tracers thanks to the empirical relationship between their heavy-element abundance and the shape of their light curves. However, the consistent a…

Near infrared and optical emission of WASP-5 b

G. Kovacs, I. Dekany, B. Karamiqucham +4

CONTEXT: Thermal emission from extrasolar planets makes it possible to study important physical processes in their atmospheres and derive more precise orbital elements. AIMS: By us…

VVV-WIT-01: highly obscured classical nova or protostellar collision?

P. W. Lucas, D. Minniti, A. Kamble +18

A search of the first Data Release of the VISTA Variables in the Via Lactea (VVV) Survey discovered the exceptionally red transient VVV-WIT-01 (). It peaked before March…

Evidence for Galactic disc RR~Lyrae stars in the Solar neighbourhood

Z. Prudil, I. Dékány, E. K. Grebel +1

We present a kinematical study of 314 RR~Lyrae stars in the solar neighbourhood using the publicly available photometric, spectroscopic, and {\it Gaia} DR2 astrometric data to expl…

On the Oosterhoff dichotomy in the Galactic bulge: II. kinematical distribution

Z. Prudil, I. Dékány, E. K. Grebel +3

We present a kinematical study of RR~Lyrae stars associated with two Oosterhoff groups in the Galactic bulge. We used data published in the first paper of the series, plus proper m…

Establishing the Galactic Centre Distance Using VVV Bulge RR Lyrae Variables

D. Majaess, I. Dékány, G. Hajdu +3

This study's objective was to exploit infrared VVV (VISTA Variables in the Via Lactea) photometry for high latitude RRab stars to establish an accurate Galactic Centre distance. RR…
