Study of the open cluster Alessi-Teutsch 9 (ASCC 10) using multiband photometry and Gaia EDR3
Nestor Sanchez, Fatima Lopez-Martinez, Sandra Ocando +1
There is a growing interest in the automated characterization of open clusters using data from the Gaia mission. This work evidences the importance of choosing an appropriate sampl…
A catalogue of open cluster radii determined from Gaia proper motions
Nestor Sanchez, Emilio Alfaro, Fatima Lopez-Martinez
In this work we improve a previously published method to calculate in a reliable way the radius of an open cluster. The method is based on the behaviour of stars in the proper moti…
A method for determining the radius of an open cluster from stellar proper motions
Nestor Sanchez, Emilio J. Alfaro, Fatima Lopez-Martinez
We propose a method for calculating the radius of an open cluster in an objective way from an astrometric catalogue containing, at least, positions and proper motions. It uses the…
Variation of the ultraviolet extinction law across the Taurus-Auriga star forming complex. A GALEX based study
Ana I. Gomez de Castro, Javier Lopez-Santiago, Fatima Lopez-Martinez +3
The Taurus-Auriga molecular complex (TMC) is the main laboratory for the study of low mass star formation. The density and properties of interstellar dust are expected to vary acro…
