Massive Stars: Their Environment and Formation

Garay Brignardello, Guido; Lizano, Susana (1999-09)

Cloud environment is thought to play a critical role in determining the mechanism of formation of massive stars. In this contribution we review the physical characteristics of the environment around recently formed massive ...

Chasing discs around O-type (proto)stars: ALMA evidence for an SiO disc and disc wind from G17.64+0.16

Maud L.T.; Cesaroni R.; Kumar M.S.N.; Van Der Tak F.F.S.; Allen V.; Hoare M.G.; Klaassen P.D.; Harsono D.; Hogerheijde M.R.; Sánchez-Monge A.; Schilke P.; Ahmadi A.; Beltrán M.T.; Beuther H.; Csengeri T.; Etoka S.; Fuller G.; Galván-Madrid R.; Goddi C.; Henning T.; Johnston K.G.; Kuiper R.; Lumsden S.; Moscadelli L.; Mottram J.C.; Peters T.; Rivilla V.M.; Testi L.; Vig S.; De Wit W.J.; Zinnecker H.

Massive protostars as gamma-ray sources

Bosch Ramon, V.; Romero, Gustavo Esteban; Araudo, Anabella Teresa; Paredes, J. M. (2010)

Three generations of stars: A possible case of triggered star formation

Areal, María Belén; Buccino, Andrea Paola; Paron, Sergio Ariel; Ortega, Martin Eduardo (Wiley Blackwell Publishing, Inc, 2020-06)

Evidence for triggered star formation linking three generations of stars is difficult to assemble, as it requires convincingly associating evolved massive stars with H ii regions that, in turn, would need to present signs ...

Core fragmentation and Toomre stability analysis of W3(H2O): A case study of the IRAM NOEMA large program CORE

Ahmadi A.; Beuther H.; Mottram J.C.; Bosco F.; Linz H.; Henning Th.; Winters J.M.; Kuiper R.; Pudritz R.; Sánchez-Monge A.; Keto E.; Beltran M.; Bontemps S.; Cesaroni R.; Csengeri T.; Feng S.; Galvan-Madrid R.; Johnston K.G.; Klaassen P.; Leurini S.; Longmore S.N.; Lumsden S.; Maud L.T.; Menten K.M.; Moscadelli L.; Motte F.; Palau A.; Peters T.; Ragan S.E.; Schilke P.; Urquhart J.S.; Wyrowski F.; Zinnecker H. (EDP Sciences, 2018)

Runaway massive stars as variable gamma-ray sources

Valle, María Victoria del; Romero, Gustavo Esteban (2014)

High spatial resolution spectroscopy of W51IRS 2E and IRS 2W: Two very massive young stars in early formation stages

BARBOSA, Cassio L.; BLUM, Robert D.; CONTI, Peter S.; DAMINELI, Augusto; FIGUEREDO, Elysandra (IOP PUBLISHING LTD, 2008)

We present K-band spectra of the near infrared counterparts to IRS 2E and IRS 2W which is associated with the ultracompact H II region W51d, both of them embedded sources in the Galactic compact H II region W51 IRS 2. The ...

APEX Millimeter Observations of Methanol Emission Toward High-mass Star-forming Cores

Hernández-Hernández, Vicente; Kurtz, Stan; Kalenskii, Sergei; Golysheva, Polina; Garay Brignardello, Guido; Zapata, Luis; Bergman, Per (Institute of Physics Publishing, 2019)

© 2019. The American Astronomical Society. All rights reserved..We present 247 GHz molecular line observations of methanol (CH3OH) toward 16 massive star-forming regions using the APEX telescope with an angular resolution ...

Fragmentation in filamentary molecular clouds

Contreras, Yanett; Garay Brignardello, Guido; Rathborne, Jill; Sanhueza, Patricio (OXFORD UNIV PRESS, 2016)

Recent surveys of dust continuum emission at sub-mm wavelengths have shown that filamentary molecular clouds are ubiquitous along the Galactic plane. These structures are inhomogeneous, with overdensities that are sometimes ...
