INVESTIGATION OF INTERACTION BETWEEN SUPERNOVA REMNANTS AND INTERSTELLAR MEDIUM
I.V. Gosachinskij, A.P. Venger, Z.A. Alferova Saint-Petersburg Branch of the Sp ecial Astrophysical Observatory of RAS 196140, Saint-Petersburg, Pulkovsko je shosse, 65, Russia gos@sao.ru During 1999-2006 the second stage of investigation of HI distribution around sup ernova remnants (SNRs) was carried out with the RATAN-600 radio telescop e. In contrast to a previous stage during 1985-87 now SNR of large angular dimension (greater than 10 ) and sp ecific typ e ­ S (shell) were selected, indep endently from their radio brightness. It is obvious that namely such ob jects have sufficiently large ages for demonstrating a evidence of interaction b etween their sho ck waves and surrounding neutral gas. Such a evidence could b e detected in the "Right Ascension ­ Velo city" ( - V ) maps as ring like structures, whose parameters may bring information ab out sizes, ages and energy of sup ernova explosion. Now we have observed ab out 130 SNRs and 105 -V maps are plotted. Some interesting ob jects (such as S147, Cygnus Lo op, HB3) were studied in detail and results were published separately. So on all - V maps will b e available at our web-site.
