Periodicity in Class II methanol masers in high-mass star-forming regions
(Oxford Univ Press, 2014)We report the results of 10 years of monitoring of six regularly varying 6.7 GHz methanol masers using the Hartebeesthoek 26-m telescope. Observations were done at intervals of 1–2 weeks, with faster sampling during ... -
Pumping of the 4.8 GHz H2CO masers and its implications for the periodic masers in G37.55+0.20
(EDP Sciences, 2014)Context. Periodic or regular flaring of class II CH3OH masers in nine high mass star forming regions is now a well established phenomenon. Amongst the nine star forming regions, G37.55+0.20 is the only case at present ...
