Homogeneous photometry and star counts in the field of 9 Galactic star clusters
(2010)
We present homogeneous $V,I$ CCD photometry of nine stellar fields in the two inner quadrants of the Galactic plane. The lines-of-view to most of these fields aim in the direction of the very inner Galaxy, where the Galactic ...
VVV-WIT-07: another Boyajian's star or a Mamajek's object?
(2019)
We report the discovery of VVV-WIT-07, a unique and intriguing variable source presenting a sequence of recurrent dips with a likely deep eclipse in 2012 July. The object was found serendipitously in the near-IR data ...
The eruption of the candidate young star asassn-15qi
(2016)
Outbursts on young stars are usually interpreted as accretion bursts caused by instabilities in the disk or the star-disk connection. However, some protostellar outbursts may not fit into this framework. In this paper, we ...

An Overview of the Rotational Behavior of Metal-poor Stars
(2009)
We describe the behavior of the rotational velocity in metal-poor stars ([Fe/H] ~ -0.5 dex) at different evolutionary stages, based on v sin i values from the literature. Our sample is composed of stars in the field and ...
L-Band Spectra of 13 Outbursting Be Stars
(2009)
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/absence of emission lines and the strength ...
