Cosmic Rulers: Masers as Tools for Probing Structure in the Galaxy and Beyond, from AU to kpc
Kazi L. J. Rygl, Anna Bartkiewicz, Olga Bayandina +9
Maser emission provides an unique window into astronomical sources across vast spatial scales - from tens to hundreds of astronomical units around protostars and evolved stars up t…
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…
Protostellar Outflows at the EarliesT Stages (POETS). VIII. The jets in the intermediate-mass star-forming region G105.42+9.88 (alias LkHα 234)
Luca Moscadelli, Fabrizio Massi, Olga Bayandina
Our aim is to investigate the protostellar jets inside the young stellar object (YSO) cluster G105.42+9.88 (alias LkH 234). This is one of the least luminous targets of the Pro…
Protostellar Outflows at the EarliesT Stages (POETS) VI. Evidence of disk-wind in G11.92-0.61 MM1
O. S. Bayandina, L. Moscadelli, R. Cesaroni +3
Magnetohydrodynamic disk-winds play a key role in the formation of massive stars by providing the fine-tuning between accretion and ejection, where excess angular momentum is redir…
