Periodic class II methanol masers in G9.62+0.20E
Van der Walt, D.J.; Goedhart, S.; Gaylard, M.J. (Oxford Univ Press, 2009)We present the light curves of the 6.7 and 12.2 GHz methanol masers in the star-forming region G9.62+0.20E for a time-span of more than 2600 d. The earlier reported period of 244 d is confirmed. The results of monitoring ... -
Periodicity in Class II methanol masers in high-mass star-forming regions
Goedhart, S.; Maswanganye, J.P.; Van der Walt, D.J.; Gaylard, M.J. (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 ... -
Short-period variability in the Class II methanol maser source G12.89+0.49 (IRAS 18089-1732)
Goedhart, S.; Langa, M.C.; Van der Walt, D.J.; Gaylard, M.J. (Oxford Univ Press, 2009)Time series are presented for the Class II methanol maser source G12.89+0.49, which has been monitored for nine years at the Hartebeesthoek Radio Astronomy Observatory. The 12.2 and 6.7 GHz methanol masers were seen to ...
