We have spectroscopically identified 60 Galactic Wolf-Rayet (WR) stars, including 38 nitrogen types (WN) and 22 carbon types (WC). Using photometry from the Spitzer/GLIMPSE and Two Micron All Sky Survey databases, the new WRs were selected via a method we have established that exploits their unique infrared colors, which is mainly the result of excess radiation generated by free-free scattering within their dense ionized winds. The selection criterion has been refined since the last report… Expand
CHARACTERIZING WOLF-RAYET STARS IN THE NEAR- AND MID-INFRARED
We present refined color-color selection criteria for identifying Wolf-Rayet (WR) stars using available mid-infrared (MIR) photometry from WISE in combination with near-infrared (NIR) photometry fromExpand
Variable dust emission by WC type Wolf–Rayet stars observed in the NEOWISE-R survey
Photometry at 3.4 and 4.6 micron of 128 Population~I WC type Wolf-Rayet stars in the Galaxy and 12 in the Large Magellanic Cloud (LMC) observed in the WISE NEOWISE-R survey was searched for evidenceExpand
WR 120bb and WR 120bc: a pair of WN9h stars with possibly interacting circumstellar shells
Two optically obscured Wolf-Rayet (WR) stars have been recently discovered by means of their infrared (IR) circumstellar shells, which show signatures of interaction with each other. Following theExpand
Discovery of a Wolf-Rayet Star through Detection of Its Photometric Variability
We report the serendipitous discovery of a heavily reddened Wolf-Rayet star that we name WR 142b. While photometrically monitoring a cataclysmic variable, we detected weak variability in a nearbyExpand
Spatial distribution of Galactic Wolf-Rayet stars and implications for the global population
We construct revised near-infrared absolute magnitude calibrations for 126 Galactic Wolf-Rayet (WR) stars at known distances, based in part upon recent large scale spectroscopic surveys. ApplicationExpand
A NEAR-INFRARED SURVEY OF THE INNER GALACTIC PLANE FOR WOLF-RAYET STARS. II. GOING FAINTER: 71 MORE NEW W-R STARS
We are continuing a J, K and narrowband imaging survey of 300 deg2 of the plane of the Galaxy, searching for new Wolf-Rayet (W-R) stars. Our survey spans 150° in Galactic longitude and reaches 1°Expand
Eleven New Heavily Reddened Field Wolf?Rayet Stars
We report the results of a medium-narrowband 2 μm line survey covering 5.8 deg^2 near the Galactic plane. We confirm 11 new field Wolf-Rayet stars along three lines of sight probing the inner Galaxy,Expand
A near-infrared survey of the inner Galactic plane for Wolf–Rayet stars – III. New methods: faintest WR stars
A new method of image subtraction is applied to images from a J, K, and narrow-band imaging survey of 300 square degrees of the plane of the Galaxy, searching for new Wolf-Rayet stars. Our surveyExpand
2MASS and WISE data analysis of Galactic Wolf-Rayet stars
We collected almost all Galactic Wolf-Rayet (hereafter WR) stars found so far from the literature. 578 WR stars are gathered in this paper. 2MASS counterparts with good quality magnitudes in all JHKExpand
Near- and Mid-Infrared colors of evolved stars in the Galactic plane. The Q1 and Q2 parameters.
Context. Mass-loss from evolved stars chemically enriches the interstellar medium (ISM). Stellar winds from massive stars and their explosions as supernovae shape the ISM and trigger star formation.Expand
