H2O maser emission from semiregular variables SZYMCZAK M., ENGELS D. <Astron. Astrophys. 296, 727 (1995)> =1995A&A...296..727S (SIMBAD/NED Reference)
ADC_Keywords: Stars, variable; Masers; Radial velocities Keywords: masers - stars: AGB, post-AGB - stars: mass-loss - surveys Description: 107 semiregular variables of spectral type M have been observed in the H2O 6(16)-5(23) line at 22.235GHz with the 100m Effelsberg radio telescope and maser emission has been detected in 23 objects, of which 10 are new detections.
