2.8 cm Radio Emission from α Orionis, HBV 475 and MWC 349

WE have used the Max-Planck-Institut 100-m telescope to search for radio emission from stars that are believed to have ejected or to be ejecting matter. Eight known radio stars were on our observing list and all were detected. Three others, α Ori, HBV 475 and MWC 349, were also detected. Three other...

Zusammenfassung:	WE have used the Max-Planck-Institut 100-m telescope to search for radio emission from stars that are believed to have ejected or to be ejecting matter. Eight known radio stars were on our observing list and all were detected. Three others, α Ori, HBV 475 and MWC 349, were also detected. Three others were possibly detected, but need further observations for confirmation. For 17 others we obtained no signal significantly greater than the r.m.s. noise. This communication concerns the three definite new detections.
