The X-ray component consisted of observations from both the ASCA and ROSAT satellites Topics: Space Radiation. Year: OAI identifier: oai: X-ray flaring from ROSAT observations in The X-ray component consisted of observations from both ROSAT (subject of this task) and ASCA satellites.
The flare event observed by ROSAT caught the astronomical hot star community by surprise because X-ray flares have not been observed from other single B-type stars, before or :// A giant X-ray flare on Lambda Eridani (B2e) Authors: Smith, Myron A.;can be fitted well to a Raymond-Smith temperature parameter of 14 MK and luminosity 4 x 10 exp 31 ergs/s; these are characteristics of giant stellar flares.
