Spectroscopic monitoring of Southern Galactic O and WN stars: State of the Art in 2007
R. Gamen, R. Barba, N. Morrell +5
We are conducting a spectroscopic monitoring of O and WN -type stars in our Galaxy. In this work, we summarize some of our first results related to the search for radial-velocity v…
Testing the predicted mass-loss bi-stability jump at radio wavelengths
P. Benaglia, J. S. Vink, J. Marti +3
In this study, we test the theoretically predicted mass-loss behaviour as a function of stellar effective temperature across the so-called `bi-stability' jump (BSJ). We gathered ra…
A uniform set of optical/NIR photometric zero points to be used with CHORIZOS
J. Maíz Apellániz
I have recently combined HST/STIS spectrophotometry with existing photometric data to analyze the calibration of three standard optical photometry systems: Tycho-2 B_TV_T, Stromgre…
A recalibration of optical photometry: Tycho-2, Strömgren, and Johnson systems
J. Maíz Apellániz
I use HST spectrophotometry to analyze the calibration of 3 optical photometry systems: Tycho-2 B_T V_T, Strömgren u v b y, and Johnson U B V. For Tycho-2, I revisit the analysis o…
The infrared Hourglass cluster in M8
J. Arias, R. Barba, J. Maiz Apellaniz +2
A detailed study of the Hourglass Nebula in the M8 star forming region is presented. The study is mainly based on recent subarcsec-resolution JHKs images taken at Las Campanas Obse…
Deriving stellar properties from photometry: maximizing information content and minimizing biases
J. Maíz Apellániz
I study the importance of the accurate calibration of photometric systems in order to produce meaningful comparisons between the observed colors + magnitudes and model SEDs. Possib…
