Dome C observations of massive protostars

open access: yes, 2008
The importance of a Dome C facility for studies of massive star formation is highlighted. Using an example of a statistical study of 380 candidate massive protostars based on the GLIMPSE legacy program data from the Spitzer Space Telescope, the ...

SpectacularSpitzerImages of the Trifid Nebula: Protostars in a Young, Massive‐Star‐forming Region

open access: yesThe Astrophysical Journal, 2006
Spitzer IRAC and MIPS images of the Trifid Nebula (M20) reveal its spectacular appearance in infrared light, highlighting the nebula's special evolutionary stage. The images feature recently-formed massive protostars and numerous young stellar objects, and a single O star that illuminates the surrounding molecular cloud from which it formed, and unveil

Dissecting high-mass protostars with SPARKS

open access: yes, 2019
The origin of the highest mass stars is still an enigma in modern astrophysics. The SPARKS project (Search for high-mass protostars with ALMA up to 5 kpc) is a high angular resolution follow-up of the complete sample of infrared quiet massive clumps ...

Search for Binary Protostars [PDF]

open access: yes, 2000
In an effort to shed more light on the formation process of binary stars, we have started a program to study multiplicity among nearby low- and intermediate-mass protostars using the OVRO Millimeter Array.

Small-scale properties of low-mass Class 0 protostars: digging into the memory of accretion processes

open access: yes, 2011
In this lecture, we briefly present the main models currently proposed to describe the collapse of prestellar dense cores and the formation of young Class 0 protostars.

Disentangling the Formation Pathways of Protostars [PDF]

open access: yes, 2023
Star formation occurs within dense cores within molecular clouds, often associated with filamentary structures. However, there exist isolated instances of star formation, far from nearby forming stars.

Variability of Deeply Embedded Protostars: A New Direction for Star Formation?

open access: yes, 2017
The formation of a star is a dynamic process fed by the gravitational collapse of a molecular cloud core. Theoretical models and observations suggest that the majority of this infalling material settles into a protoplanetary disk before reaching the (proto)star and therefore that disk accretion processes are responsible for the rate at which the (proto)
