... The object is remarkable because of its low estimated mass and age and because it is associated with a mid-infrared source, an indication of a surrounding dusty disk. Based on the comparison of our spectrum with similar spectra of field M-dwarfs and atmospheric models, we obtain revised estimates of the spectral type, effective temperature and luminosity of the central object. ...

Evidence against the association of PSR B1706-44 with SNR G343.1-2.3 . ... Abstract An association between the supernova remnant SNR G343.1-2.3 and the pulsar PSR B1706-44 would imply a pulsar velocity greater than 1000 km/s. Observations of the pulsar scintillation made with the Parkes radio telescope at 20 and 70 cm indicate a velocity less than 50 km/s. This fact, coupled with statistical arguments and the morphology of both the SNR and the pulsar plerion, shows that the ...

We review the evidence, from rotational modulation, for association of plages and spots on active binaries. ... There is a similar lack of evidence for BY Dra systems. The results can be interpreted as evidence for: (a) the presence of active longitudes which persist on some RS CVn stars for several years, (b) high filling factors in MgII emission and (c) lower filling factors, and therefore greater contrast, in SWP emission. ...
