Spectral classification of brown dwarfs using machine learning
A. R. Callen, I. H. Bustos Fierro, M. Gómez
Brown dwarfs are compact objects that do not reach temperatures high enough to produce sustained hydrogen fusion. Consequently, they cool over time, gradually evolving through late…
Variable stars in the field of the Galactic globular cluster M71
C. C. Cortés, D. Deras, A. Arellano Ferro +2
M71 is a nearby, metal-rich globular cluster at low Galactic latitude, where field contamination and spatially variable extinction complicate colour-magnitude diagrams (CMDs) and t…
The variable stars population of the extended young globular cluster NGC 1851
A. Arellano Ferro, C. E. Pérez Parra, M. A. Yepez +3
We report VI CCD photometry of the globular cluster cluster NGC 1851. We aim to study the membership of the variable stars detected in the field of the cluster as listed in the Cat…
The variable stars in the field of the bulge cluster NGC 6558
A. Arellano Ferro, L. J. Zerpa Guillen, M. A. Yepez +3
We made a survey of the variable stars in a arcmin centered on the field of the Galactic bulge cluster NGC 6558. A total of 78 variables was found in the fie…
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…
A new study of the variable star population in the Hercules globular cluster (M13; NGC 6205)
D. Deras, A. Arellano Ferro, C. Lázaro +4
We present the results from CCD time-series photometry of the globular cluster M13 (NGC 6205). From the Fourier decomposition of the light curves of RRab and RRc stars we foun…
