Far-infrared observations of chromospherically active stars in stellar clusters.


Abstract (from CDS):

Using the IRAS database we have searched for far-infrared emission from a large number of chromospherically active dwarf stars (including flare stars) in stellar clusters of different ages and distances. Only stars in the nearest clusters (<50pc) were detected by IRAS. Their 12µm luminosity (L12) is in the range 0.2-5x1031erg/s. We find that the detected emission is photospheric in origin and that there is no correlation of flux either with age or with stellar-activity levels. The cluster stars' far-infrared radiation characteristics are very similar to those of solar-vicinity field stars of similar spectral type and chromospheric activity.
