Metallicity estimation of RR Lyrae stars from their I-band light curves
István Dékány, Eva K. Grebel, Grzegorz Pojmański
We have revisited the problem of metallicity prediction of RR Lyrae stars from their near-infrared light curves in the Cousins I waveband. Our study is based on high-quality time-s…
Near-Infrared Search for Fundamental-mode RR Lyrae Stars Toward the Inner Bulge by Deep Learning
István Dékány, Eva K. Grebel
Aiming to extend the census of RR Lyrae stars to highly reddened low-latitude regions of the central Milky Way, we performed a deep near-IR variability search using data from the V…
Into the Darkness: Classical and Type II Cepheids in the Zona Galactica Incognita
István Dékány, Gergely Hajdu, Eva K. Grebel +1
The far side of the Milky Way's disk is one of the most concealed parts of the known Universe due to extremely high interstellar extinction and point source density toward low Gala…
On the optimal calibration of VVV photometry
Gergely Hajdu, István Dékány, Márcio Catelan +1
Prompted by some inconsistencies in the photometry of the VISTA Variables in the Vía Láctea (VVV) survey, we conduct a revision of the standard calibration procedure of VISTA data…
On the Oosterhoff dichotomy in the Galactic bulge: I. spatial distribution
Z. Prudil, I. Dékány, M. Catelan +3
We present a study of the Oosterhoff (Oo) dichotomy in the Galactic bulge using 8\,141 fundamental mode RR~Lyrae stars. We used public photometric data from the Optical Gravitation…
Photometric study of the SMCNOD using variable stars from the OGLE-IV survey
Z. Prudil, E. K. Grebel, I. Dékány +1
We present a study of a recently discovered stellar overdensity near the northern edge of the Small Magellanic Cloud (SMCNOD). We exploited variable stars from the fourth release o…
