The IACOB project: synergies for the Gaia era
S. Simón-Díaz, M. Garcia, A. Herrero +2
The IACOB spectroscopic survey of Galactic OB stars is an ambitious observational project aimed at compiling a large, homogeneous, high-resolution database of optical spectra of ma…
The Galactic O-Star Spectroscopic (GOSSS) and Northern Massive Dim Stars (NoMaDS) Surveys, the Galactic O-Star Catalog (GOSC), and Marxist Ghost Buster (MGB)
J. Maíz Apellániz, A. Pellerin, R. H. Barbá +6
There are several ongoing massive-star (mostly of spectral type O) surveys that are significantly increasing the quality and quantity of the spectroscopic information about these o…
The 100 Myr Star Formation History of NGC 5471 from Cluster and Resolved Stellar Photometry
Rubén García-Benito, Enrique Pérez, Ángeles I. Díaz +2
We show that star formation in the giant HII region NGC 5471 has been ongoing during the past 100 Myr. Using HST/WFPC2 F547M and F675W, ground based JHKs, and GALEX FUV and NUV ima…
The Galactic O-Star Spectroscopic Survey. I. Classification System and Bright Northern Stars in the Blue-Violet at R~2500
A. Sota, J. Maíz Apellániz, N. R. Walborn +5
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…
Science with the Galactic O-Star Spectroscopic Survey (GOSSS) : The relationship between DIBs, ISM, and extinction
Miguel Penadés Ordaz, Jesús Maíz Apellániz, Alfredo Sota Ballano +6
In this poster we show our preliminary analysis of DIBs (Diffuse Interstellar Bands) and other interstellar absorption lines with the purpose of understanding their origin and thei…
The Galactic O-Star Spectral Survey (GOSSS) Project status and first results
Alfredo Sota, Jesús Maíz Apellániz, Rodolfo H. Barbá +6
The Galactic O-Star Spectroscopic Survey (GOSSS) is a project that is observing all known Galactic O stars with B < 13 (~2000 objects) in the blue-violet part of the spectrum with…
