Detections of Compact Radio Continuum toward Methanol Maser Rings Using the VLA
Anna Bartkiewicz, Olga Bayandina, Alberto Sanna +5
High-mass protostars are deeply embedded in dust inside their natal cores and are not easily detectable. However, maser emission at centimeter wavelengths, owing to its high bright…
A search for the favored hyperfine transition of a 6.7 GHz methanol maser line
A. Kobak, G. Surcis, A. Bartkiewicz +2
The polarized emission of astrophysical masers, especially OH and methanol lines, is an effective tool to study the magnetic field in high-mass star-forming regions. The magnetic f…
Discovery of synchronized periodic variability of methanol maser features in G26.598-0.024
P. Wolak, M. Szymczak, A. Kobak +5
Aims. We report the discovery of periodic maser variability of an unusual pattern in the high-mass young stellar object G26.598-0.024. Methods. A ten-year monitoring of the 6.7 GHz…
Physical conditions around high-mass young star-forming objects via simultaneous observations of excited OH and methanol masers
A. Kobak, A. Bartkiewicz, K. L. J. Rygl +3
Astrophysical masers are widely used in star formation studies. In particular, they are valuable in investigations of high-mass star-forming regions that are difficult to observe a…
Proper motion study of the 6.7 GHz methanol maser rings. I. A sample of sources with little variation
A. Bartkiewicz, A. Sanna, M. Szymczak +5
Methanol masers at 6.7~GHz are well-known signposts of high-mass star-forming regions. [...] We aim to understand the origin of the ring-like structures outlined by methanol maser…
Seven-year periodic variations in the methanol maser line displayed by the massive protostar IRAS 20216+4104
M. Szymczak, M. Durjasz, S. Goedhart +5
Aims: We report the discovery and analysis of a periodic methanol maser in the massive protostar IRAS 20216+4104. Methods: To obtain the light curve, we used the 6.7 GHz methanol m…
Milliarcsecond structure and variability of methanol maser emission in three high-mass protostars
A Aberfelds, A Bartkiewicz, M Szymczak +5
{The variability study of 6.7\,GHz methanol masers has become a useful way to improve our understanding of the physical conditions in high-mass star-forming regions.} {Based on the…
Multi-frequency VLBI observations of maser lines during the 6.7~GHz maser flare in the high-mass young stellar object G24.330.14}
A. Kobak, A. Bartkiewicz, M. Szymczak +13
Recent studies have shown that 6.7 GHz methanol maser flares can be a powerful tool for verifying the mechanisms of maser production and even the specific signatures of accretion r…
