SPICY 30021: an embedded bona fide FUor with a mid-infrared precursor
Zhen Guo, Calum Morris, Vitor Fermiano +37
Unstable mass accretion in young stellar objects (YSOs) often leads to observable outbursts, which play a key role in stellar mass assembly during pre-main-sequence evolution. The…
Unresolved triples in the open cluster NGC 2437 (M 46) confirmed by the KMOS VVVX-GalCen Spectroscopic Survey
D. Minniti, T. Palma, C. O. Obasi +31
Recent optical and near-IR photometric databases like Gaia data release 3 (DR3) and the VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey allow the exploration of…
Variable stars in the field of the Galactic bulge globular cluster NGC 6522
A. Arellano Ferro, Z. Prudil, M. A. Yepez +2
We present a comprehensive analysis of the variable stars projected on the field of the Galactic bulge globular cluster NGC 6522, offering valuable insights into their characterist…
The variable stars in the field of NGC 6139: A critical approach to their reddening and membership
M. A. Yepez, A. Arellano Ferro, I. Bustos Fierro +1
We present a CCD time-series analysis of the globular cluster NGC 6139 and its variable star population. Using the astrometric data available in -DR3 we performed a memb…
Secular period variations of RR Lyrae stars in NGC 4147
Alonso Luna, Armando Arellano Ferro
A compilation of photometric time-series data of NGC 4147 spanning 58 years, enabled to study the secular behaviour of the pulsation period in the population of RR Lyrae stars in t…
Period changes in the RR Lyrae stars of NGC 6171 (M107)
A. Arellano Ferro, P. Rosenzweig, A. Luna +4
Based on photometric data obtained between 1935 and 2017, diagrams were built for 22 RR Lyrae stars in the globular cluster NGC 6171, leading to the discovery of secular peri…
