A detailed study of lithium in 107 CHEPS dwarf stars
(EDP Sciences, 2018)
Context. We report results from lithium abundance determinations using high resolution spectral analysis of the 107 metal-rich stars from the Calan-Hertfordshire Extrasolar Planet Search programme.
Aims. We aim to set ...
Further results from the galactic O-Star Spectroscopic Survey: rapidly rotating late ON giants
(Iop Publishing, 2011-11)
With new data from the Galactic O-Star Spectroscopic Survey, we confirm and expand the ONn category of late-O, nitrogen-enriched (N), rapidly rotating (n) giants. In particular, we have discovered two “clones” (HD 102415 ...
Near-IR period-luminosity relations for pulsating stars in ω Centauri (NGC 5139)
(Astronomy and Astrophysics, 2017-08)
Aims. The globular cluster ω Centauri (NGC 5139) hosts hundreds of pulsating variable stars of different types, thus representing a treasure trove for studies of their corresponding period-luminosity (PL) relations. Our ...
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 Galactic O-Star Spectroscopic Survey, I: Classification System and Bright Northern Stars in the blue-violet at R ~ 2500
(Iop Publishing, 2011-04)
We present the first installment of a massive spectroscopic survey of Galactic O stars, based on new, high signal-to-noise ratio, R ~ 2500 digital observations from both hemispheres selected from the Galactic O-Star Catalog ...
The Galactic O-Star Spectroscopic Survey (GOSSS). II : bright southern stars
(Iop Publishing, 2014-03)
We present the second installment of GOSSS, a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R ~ 2500 digital observations from both hemispheres selected from the ...
The SOFIA massive (SOMA) star formation survey. I. Overview and first results
(IOP Publishing Ltd., 2017)
We present an overview and first results of the Stratospheric Observatory For Infrared Astronomy Massive (SOMA) Star Formation Survey, which is using the FORCAST instrument to image massive protostars from similar to 10 ...
