A Keplerian disk with a four-arm spiral birthing an episodically accreting high-mass protostar
R. A. Burns, Y. Uno, N. Sakai +34
High-mass protostars (M 8 M) are thought to gain the majority of their mass via short, intense bursts of growth. This episodic accretion is thought to be faci…
A heat-wave of accretion energy traced by masers in the G358-MM1 high-mass protostar
R. A. Burns, K. Sugiyama, T. Hirota +20
High-mass stars are thought to accumulate much of their mass via short, infrequent bursts of disk-aided accretion. Such accretion events are rare and difficult to observe directly…
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…
Evidence for cold plasma in planetary nebulae from radio observations with the LOw Frequency ARray (LOFAR)
Marcin Hajduk, Marijke Haverkorn, Timothy Shimwell +6
We present observations of planetary nebulae with the LOw Frequency ARray (LOFAR) between 120 and 168 MHz. The images show thermal free-free emission from the nebular shells. We ha…
Infrared observations of the flaring maser source G358.93-0.03 -- SOFIA confirms an accretion burst from a massive young stellar object
B. Stecklum, V. Wolf, H. Linz +24
Class II methanol masers are signs of massive young stellar objects (MYSOs). Recent findings show that MYSO accretion bursts cause flares of these masers. Thus, maser monitoring ca…
Long-term multi-frequency maser observations of the intermediate-mass young stellar object G107.298+5.639
Mateusz Olech, Marian Szymczak, Paweł Wolak +2
Periodic flares of maser emission are thought to be induced either by variations of the seed photon flux in young binary systems or the pump rate regulated by stellar and accretion…
