300: An ACA 870 μm Continuum Survey of Orion Protostars and Their Evolution

open access: yesThe Astrophysical Journal, 2023
We present an 870 μ m continuum survey of 300 protostars from the Herschel Orion Protostar Survey using the Atacama Compact Array (ACA). These data measure protostellar flux densities on envelope scales ≤8000 au (20″) and resolve the structure of ...

What Can Meteorites Tell Us About the Formation of Jupiter?

open access: yesAGU Advances, Volume 2, Issue 2, June 2021., 2021
Abstract Gas giants like Jupiter are a fundamental component of planetary systems, but how they formed has been uncertain. Here we discuss how paleomagnetic records in meteorites of the solar nebula may tell us about Jupiter's final growth stage. We suggest that under certain testable assumptions, the meteorite data indicate that proto‐Jupiter grew ...

Magnetic Effects Promote Supermassive Star Formation in Metal-enriched Atomic-cooling Halos

open access: yesThe Astrophysical Journal, 2023
Intermediate-mass black holes (with ≥10 ^5 M _⊙ ) are promising candidates for the origin of supermassive black holes (with ∼10 ^9 M _⊙ ) in the early universe (redshift z ∼ 6).

Far infrared CO and H$_2$O emission in intermediate-mass protostars [PDF]

open access: yes, 2015
Intermediate-mass young stellar objects (YSOs) provide a link to understand how feedback from shocks and UV radiation scales from low to high-mass star forming regions.

Predicted Colors and Flux Densities of Protostars in the Herschel PACS and SPIRE Filters [PDF]

open access: yes, 2010
Upcoming surveys with the Herschel Space Observatory will yield far-IR photometry of large samples of young stellar objects, which will require careful interpretation.

Protostellar jets: A statistical view with the CALYPSO IRAM-PdBI survey [PDF]

open access: yesEPJ Web of Conferences, 2022
In the context of the CALYPSO IRAM-PdBI Lai•ge Program we performed the first statistical survey of protostellar jets by analysing molecular emission in a sample of 21 protostars covering a broad range of internal luminosities (Lint from 0.035 L⊙ to 47 L⊙

The Power of SOFIA/FORCAST in Estimating Internal Luminosities of Low Mass Class 0/I Protostars [PDF]

open access: yes, 2017
With the Stratospheric Observatory for Infrared Astronomy (SOFIA) routinely operating science flights, we demonstrate that observations with the Faint Object infraRed CAmera for the SOFIA Telescope (FORCAST) can provide reliable estimates of the internal
