Low-energy X-ray observations of the Wolf 630 SYSTEM
Description
The Exosat channel multiplier array is used to resolve the septuplet of M dwarfs into three components (Wolf 630ABab, Wolf 629ab, and VB 8AB) with widely different X-ray characteristics. An isothermal plasma temperature of between 800,000 and 550,000 K (which is very low in the known range of coronal temperatures) is found for any relatively quiescent state of VB 8. It is shown from the count rate during 18,112 sec of effective exposure with Exosat that VB 8 flared once in 0.05-2 keV flux. 27 references
