| Betreff des Beitrags: | [spectro-l] P Cygni from Texas Star Party |
In einer eMail vom 20.05.2007 03:41:18 Westeuropäische Normalzeit schreibt keith schlottman: Zitat: I?m working on attempting to calculate the radial velocity of the shell from the blueshifted absorption; of course it will be rather a rough approximation. Does anyone know of an ?accepted? value?
Hi Keith,This is a compressed jpeg, for a better version with more details about integration times etc. see: http://www.xanaduobservatory.com/p_cygni.htm my colleague Bernd Hanisch (near Frankfurt/Oder, former East-Germany) calculated several times RV of lines in spectra of P Cygni. For you it seems to make sense to have contact to him. Here his eMail adress: bernd.hanisch(==>)... I hope you will have a constructive cooperation!! Best wishes, Ernst Pollmann |
