The physics of star cluster formation and evolution

MGH Krause, SSR Offner, C Charbonnel… - Space Science …, 2020 - Springer
Star clusters form in dense, hierarchically collapsing gas clouds. Bulk kinetic energy is
transformed to turbulence with stars forming from cores fed by filaments. In the most compact …

Zooming in on individual star formation: low-and high-mass stars

AL Rosen, SSR Offner, SI Sadavoy, A Bhandare… - Space Science …, 2020 - Springer
Star formation is a multi-scale, multi-physics problem ranging from the size scale of
molecular clouds (∼ 10 ∼10 s pc) down to the size scales of dense prestellar cores (∼ 0.1 …

Water in star-forming regions: physics and chemistry from clouds to disks as probed by Herschel spectroscopy

EF van Dishoeck, LE Kristensen, JC Mottram… - Astronomy & …, 2021 - aanda.org
Context. Water is a key molecule in the physics and chemistry of star and planet formation,
but it is difficult to observe from Earth. The Herschel Space Observatory provided …

Imaging the water snow-line during a protostellar outburst

LA Cieza, S Casassus, J Tobin, SP Bos, JP Williams… - Nature, 2016 - nature.com
A snow-line is the region of a protoplanetary disk at which a major volatile, such as water or
carbon monoxide, reaches its condensation temperature. Snow-lines play a crucial role in …

The Herschel Orion protostar survey: spectral energy distributions and fits using a grid of protostellar models

We present key results from the Herschel Orion Protostar Survey: spectral energy
distributions (SEDs) and model fits of 330 young stellar objects, predominantly protostars, in …

Variable protostellar accretion with episodic bursts

EI Vorobyov, S Basu - The Astrophysical Journal, 2015 - iopscience.iop.org
We present the latest development of the disk gravitational instability and fragmentation

Signs of early-stage disk growth revealed with ALMA

HW Yen, PM Koch, S Takakuwa… - The Astrophysical …, 2017 - iopscience.iop.org
We present ALMA 1.3 mm continuum, 12 CO, C 18 O, and SO data for the Class 0 protostars
Lupus 3 MMS, IRAS 15398− 3559, and IRAS 16253− 2429 at resolutions of∼ 100 au. By …

A likely flyby of binary protostar Z CMa caught in action

R Dong, HB Liu, N Cuello, C Pinte, P Ábrahám… - Nature …, 2022 - nature.com
Close encounters between young stellar objects in star-forming clusters are expected to
markedly perturb circumstellar disks. Such events are witnessed in numerical simulations of …

The Rate, Amplitude, and Duration of Outbursts from Class 0 Protostars in Orion

W Zakri, ST Megeath, WJ Fischer… - The Astrophysical …, 2022 - iopscience.iop.org
At least half of a protostar's mass is accreted in the Class 0 phase, when the central protostar
is deeply embedded in a dense, infalling envelope. We present the first systematic search …
