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

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

MASERS AS TRACERS OF ANGULAR MOMENTUM IN MOLECULAR OUTFLOWS
Tecnociencia, 2023 The dissipation of angular momentum of collapsing molecular cores is a key component in the formation of stars. Previous observations have reported that highly collimated protostellar jets can remove angular momentum from low-mass protostars.

Merger Conditions of Population III Protostar Binaries
The Astrophysical Journal, 2023 Massive close binary stars with extremely small separations have been observed, and they are possible progenitors of gravitational-wave sources. The evolution of massive binaries in the protostellar accretion stage is key to understanding their formation

CO in Protostars (COPS): $Herschel$-SPIRE Spectroscopy of Embedded Protostars [PDF]
, 2018 We present full spectral scans from 200-670$\mu$m of 26 Class 0+I protostellar sources, obtained with $Herschel$-SPIRE, as part of the "COPS-SPIRE" Open Time program, complementary to the DIGIT and WISH Key programs.

The Mass Accretion Rate and Stellar Properties in Class I Protostars
The Astrophysical Journal, 2023 Stars collect most of their mass during the protostellar stage, yet the accretion luminosity and stellar parameters, which are needed to compute the mass accretion rate, are poorly constrained for the youngest sources.

Molecular richness in protostars: Lessons learnt from spectral observations [PDF]
EPJ Web of Conferences, 2022 The gas associated with the early stages of star formation contains traces of a large variety of molecular species, many of which are organic in nature. Interestingly, we observe a substantial chemical diversity among protostars, with some objects being ...

A radiation driven implosion model for the enhanced luminosity of protostars near HII regions [PDF]
, 2006 Context. Molecular clouds near the H II regions tend to harbor more luminous protostars. Aims. Our aim in this paper is to investigate whether or not radiation-driven implosion mechanism enhances luminosity of protostars near regions of high-ionizing ...

Clustered Star Formation in W75 N [PDF]
, 2002 We present 2" to 7" resolution 3 mm continuum and CO(J=1-0) line emission and near infrared Ks, H2, and [FeII] images toward the massive star forming region W75 N. The CO emission uncovers a complex morphology of multiple, overlapping outflows.
