We report preliminary results of monitoring the flux from the Wolf-Rayet object WR 146 with the Westerbork Synthesis Radio Telescope at 21 cm since 1989. We find the average flux density slowly rising in the period 1989-1997, with evidence of shorter

WSRT 21-cm continuum field in Cygnus OB2: in search of more Wolf-Rayet stars

We present a deep look into the Cygnus OB2 region using the WSRT. A 2degrees x 2degrees map of the optically highly-obscured region was obtained at 1400 MHz, with a noise level down to 0.2 mJy and an angular resolution of 1". We will compare the resu

The Hipparcos distance determination of the Wolf-Rayet system gamma(2) Velorum (WC8+O) and its ramifications

Autor: vanderHucht, KA, Schrijver, H, Stenholm, B, Lundstrom, [No Value], Moffat, AFJ, Marchenko, SV, Seggewiss, W, Gunawan, DYAS, Sutantyo, W, vandenHeuvel, EPJ, DeCuyper, JP, Gomez, AE

Publikováno v: New Astronomy, 2(3), 245-250. ELSEVIER SCIENCE BV

Hipparcos parallax measurements give a distance to the Wolf-Rayet WC8 + O spectroscopic binary gamma(2) Vel of d = 258(-31)(+41) pc and a distance to the O4I(n)f star zeta Pup of d = 429(-77)(+120) pc. Adopting for gamma(2) Vel an interstellar extinc

An Infrared Study Of 3 Wolf-rayet Ring Nebulae

Autor: MATHIS, JS, CASSINELLI, JP, VANDERHUCHT, KA, PRUSTI, T, Wesselius, P. R., WILLIAMS, PM

Publikováno v: Astrophysical Journal, 384(1), 197-211. IOP PUBLISHING LTD

We have studied the IRAS colors of the ring nebula RCW 58 surrounding the Wolf-Rayet star HD 96548 (= WR 40; type WN 8) by analyzing the IRAS survey data with the Groningen Exportable High-Resolution Analysis system (GEISHA) and by using the Chopped
