Red Be stars in the Magellanic Clouds?
Katherine Vieira, Alejandro García-Varela, Beatriz Sabogal +2
We revisit the subject of Be star candidates towards the Magellanic Clouds, previously studied by the authors using SPM4 proper motions. We obtain GAIA DR2 parallaxes and proper mo…
Machine learning techniques to select Be star candidates. An application in the OGLE-IV Gaia south ecliptic pole field
M. F. Pérez-Ortiz, A. García-Varela, A. J. Quiroz +2
Statistical pattern recognition methods have provided competitive solutions for variable star classification at a relatively low computational cost. In order to perform supervised…
Proper motion separation of Be star candidates in the Magellanic Clouds and the Milky Way
Katherine Vieira, Alejandro García-Varela, Beatriz Sabogal
We present a proper motion investigation of a sample of Be star candidates towards the Magellanic Clouds, which has resulted in the identification of separate populations, in the G…
The influential effect of blending, bump, changing period and eclipsing Cepheids on the Leavitt law
A. García-Varela, J. R. Muñoz, B. E. Sabogal +2
The investigation of the non-linearity of the Leavitt law is a topic that began more than seven decades ago, when some of the studies in this field found that the Leavitt law has a…
A Study on the Universality and Linearity of the Leavitt Law in the LMC and SMC Galaxies
Alejandro García-Varela, Beatriz Sabogal, María Ramírez-Tannus
The universality and linearity of the Leavitt law are hypotheses commonly adopted in studies of galaxy distances using Cepheid variables as standard candles. In order to test these…
L-band spectra of 13 outbursting Be stars
R. E. Mennickent, B. Sabogal, A. Granada +1
We present new L-band spectra of 13 outbursting Be stars obtained with ISAAC at the ESO Paranal observatory. These stars can be classified in three groups depending on the presence…
