WRCAT - The VIIth Catalog of Galactic Wolf-Rayet Stars


Overview

The VIIth Catalogue of Galactic Population I Wolf-Rayet (WR) Stars provides improved coordinates, spectral types, and bv photometry of known WR stars and adds 71 new stars compared to the VIth Catalog. This census of galactic WR stars has reached 227 stars (226 entries in this catalog), comprising 127 WN stars, 87 WC stars, 10 WN/WC stars, and 3 WO stars. This includes 15 WNL and 11 WCL stars within 30 pc of the Galactic Center. The catalog includes information on periodicity, binarity, terminal wind velocities, correlations with open clusters, OB associations, H I bubbles, H II regions, and ring nebulae, observed and dereddened narrow-band bv photometry, and distances, both heliocentric and galactocentric, and lists the references from which this information was obtained.

Catalog Bibcode

2001NewAR..45..135V

References

`The VIIth Catalogue of Galactic Wolf-Rayet Stars', K.A. van der Hucht 2001, New Astronomy Reviews 45, 135.

Provenance

This catalog was created by the HEASARC in April 2001, based on electronic versions of Tables 13, 14, 15, and 28 from the published paper containing the catalog which were directly supplied to the HEASARC by the author.

Parameters

Name
The Wolf-Rayet Catalog designation, essentially a running number in order of increasing RA, based on the VIth Catalogue (van der Hucht et al. 1981, SSR 28, 227) running number with new stars being given intermediate designations, e.g., WR 102k. Notice that the WR star SMSP 4, labelled WR 31a by Shara et al. (1991) is here designated WR 31c, the WR star SMSNPL 8 labelled WR 48a by Shara et al. (1999) is here designated WR 48b, and that the WR star SMSNPL 17 labelled WR 102i by Shara et al. (1999) is here designated WR 102l.

Vmag
The apparent v magnitude in the narrow-band ubv system of Smith (1968a, MNRAS 138,109) chosen to avoid the strongest WN emission lines. This is the observed value except in the case of the heavily reddened WR stars near the Galactic Center for which it is the inferred value based on their IR magnitudes.

Vmag_Flag
This is a flag for the v magnitude, where "(" and ":" indicate an uncertain value, and ">" that the quoted value is an upper limit.

BV_Color
The apparent b-v color in the narrow-band ubv system of Smith (1968a, MNRAS 138,109) chosen to avoid the strongest WN emission lines. This is the observed value except in the case of the heavily reddened WR stars near the Galactic Center for which it is the inferred value based on their IR magnitudes.

The observed orbital period or periodicities, in days.

Binary_Status
The binary status of the WR star, where SB means spectroscopic binary (SB1 single-lined SB, and SB2 double-lined SB), VB means visual binary, CWB means colliding wind binary, a means absorption line(s) are present in the optical spectrum, and d.e.l. means diluted emission lines are present.

BV_Color_0
The intrinsic (i.e., dereddened) narrow-band b-v color.

E_BV
The selective extinction in the narrow-band b-v color, E(b-v).

Reddening
The total extinction or reddening in the narrow-band v, A(v), calculated using the relation A(v) = 4.1 * E(b-v).

Vmag_0
The intrinsic (i.e., dereddened) narrow-band v Magnitude.

Abs_Vmag_Wr
The derived absolute v magnitude of the WR star, or (if in a multiple system) of the WR star component, M(v)_WR.

Delta_M
The inferred magnitude difference, delta_m, between the other component and the WR star component if a multiple system. If the WR star is brighter than the other component, delta_m is positive, whereas if the WR star is fainter than the other component, delta_m is negative.

Abs_Vmag_Sys
The derived absolute v magnitude of the multiple system containing the WR star, M(v)_sys. This is related to the absolute v magnitude of the WR star, M(v)_WR, and the magnitude difference between the components, delta_m, by the relation: M(v)_sys = M(v)_WR -2.5*log10(1+10^(-delta_m/2.5)).

True_Dm
The true distance modulus of the WR star, DM_0, in magnitudes, where DM_0 = 5*log10(D) + 10, where D is the distance to the WR star in kiloparsecs.

Distance
The (heliocentric) distance to the WR star, in kiloparsecs (kpc).

Z_Distance
The distance z that the WR star lies above or below the galactic plane, in parsecs (pc).

Gc_Distance
The distance of the WR star from the Galactic Center, in kiloparsecs (kpc).

Note_Flag
This flag is set to "Y" if there are notes on the star in the published version of the catalog (q.v.).

Class
The HEASARC Browse object classification, based on the spectral type parameter value.
