Special Astrophysical Observatory, St. Petersburg Branch, Russian Academy of Sciences, 196140, Pulkovo, St. Petersburg, Russia aut Neutral hydrogen in the vicinity of the supernova remnant HB 9 [Elektronische Daten] [I. Gosachinskii] The neutral hydrogen emission at 21 cm has been investigated with the RATAN-600 radio telescope in the vicinity of the supernova remnant HB9. A clumpyHI shell with radial motions surrounding the remnant has been detected. Its measured parameters contradict the connection with a shock wave from a supernova explosion. The shell formation under the action of a wind from a star that exploded as a supernova at the end of its evolution seems more realistic. The characteristics of the star obtained from the observed shell parameters are the following: a wind power of 0.5 × 1038 erg s−1, a mass-loss rate of 3.7 × 10−5 M ⊙ yr−1, and an age of 3 × 106 yr. Given the measurement errors, the mass of the star is estimated to be >8M ⊙.
