In June 2014, the Faculty of Astronomical and Geophysical Sciences of the National University of La Plata, Argentina, received a telescope as a donation from the family of Dr. Rafael Montemayor. This instrument was a personal project of the professor

The southern open cluster NGC 4852 was re-observed in the UBVRI passbands to refine its intrinsic fundamental parameters. An extended spectral coverage was also undertaken aimed at obtaining a clear picture of the kind of stars inhabiting the cluster

We present results of a study that combines UBV I photometry, MK spectral classification and proper motions in the area of the, up to now unknown, open cluster Ruprecht 58 at the Puppis region. Star counts from the 2MASS data catalog to- gether with

We describe a code to determine the initial and present mass of a star in the HR diagram. The code is based on an interpolation procedure between the two adjacent evolutionary tracks where the star is situated according to its luminosity and temperat

Employing the statistical analysis of Muzyliev (1978, Nauch. Inform. Astronom. Council USSR Acad. Sci. 41, 94) we have made a code for obtaining the mass of a star, if the two evolutionary tracks along which it lies are known. The code has been adapt

A code that allows us to obtain the mass of an isolated star (see: Code for calculating the mass of a star onto the HR diagram, 1993; S. Paoli et al.) from its position in the observational HR diagram is devoted to the determination of the total obse

Hemos construido un catálogo de estrellas OB de nuestra galaxia que contiene información fotométrica (Bandas UBVRI-JHKLM), espectroscópica (tipos espectrales MK) así como conclusiones sobre binaridad (elementos orbitales si los hay determinados)

In the present paper we completely introduce the method to develop a celestial objects taxonomy. The steps to follow are shown and its way of application explained. They are also given the preliminary results obtained when studying association with m

El material provisto por 47 cúmulos abiertos muy jóvenes ha sido utilizado para varios estudios que conciernen a la situación evolucionaría de estrellas de más de 10 masas solares. Se hizo una discusión sobre índices de colores y se midió el

Se han compilado datos fotométricos y espectroscópicos de 54 estrellas de tipo Of pertenecientes a 21 cúmulos abiertos jóvenes. Todos ellos resultan ser objetos de alta luminosidad y evolucionados respecto de la ZAMS. Su posición en el diagrama
