New radial systems of dark globules
(UNAM, Instituto de Astronomía, 2015)
We present the results of a systematic survey of ESO/SRC plates of the Southern Hemisphere aimed at discovering new radial systems of dark globules. During this survey, we found 16 new type 1 radial systems and 6 type 2 ...
The stellar content of obscured Galactic giant H II regions. VI. W51A
(IOP PUBLISHING LTD, 2008)
We present K-band spectra of newly born OB stars in the obscured Galactic giant H II region W51A and approximate to 0.8 '' angular resolution images in the J, H, and K(S)-bands. Four objects have been spectroscopically ...
A Hubble Space Telescope/NICMOS view of the prototypical giant H ii region NGC604 in M33
(Springer, 2009-12)
We present the first high-spatial-resolution nearinfrared (NIR) imaging of NGC604, obtained with the NICMOS camera onboard the Hubble Space Telescope (HST). These NICMOS broad-band images reveal new NIR point sources, ...

HI bubbles surrounding southern optical ring nebulae: Anon(WR 23) and RCW 52
(EDP Sciences, 2005-12)
We analyze the interstellar medium in the environs of two hot and massive stars, HD 92809 (= WR 23, WC6) and LSS 1887 (O8V), which ionize the optical ring nebulae Anon(WR 23) and RCW 52, respectively. Our analysis is based ...
Spectroscopic study of the N159/N160 complex in the Large Magellanic Cloud
(IOP Publishing, 2009-12)
We present a spectroscopic study of the N159/N160 massive star-forming region south of 30 Doradus in the Large Magellanic Cloud, classifying a total of 189 stars in the field of the complex. Most of them belong to O and ...
