V838 Mon: A slow waking up of Sleeping Beauty?

T. Liimets, I. Kolka, M. Kraus +15

Context. V838 Monocerotis is a peculiar binary that underwent an immense stellar explosion in 2002, leaving behind an expanding cool supergiant and a hot B3V companion. Five years…

The Herschel-PACS legacy of low-mass protostars: Properties of warm and hot gas and its origin in far-UV illuminated shocks

Agata Karska, Michael J. Kaufman, Lars E. Kristensen +11

Recent observations from Herschel allow the identification of important mechanisms responsible for the heating of gas surrounding low-mass protostars and its subsequent cooling in…

Externally heated protostellar cores in the Ophiuchus star-forming region

Johan E. Lindberg, Steven B. Charnley, Jes K. Jørgensen +2

We present APEX 218 GHz observations of molecular emission in a complete sample of embedded protostars in the Ophiuchus star-forming region. To study the physical properties of the…

On the origin of CH and CHOH in protostellar envelopes

Johan E. Lindberg, Steven B. Charnley, Martin A. Cordiner

The formation pathways of different types of organic molecules in protostellar envelopes and other regions of star formation are subjects of intense current interest. We here prese…

Water around IRAS15398-3359 observed with ALMA

P. Bjerkeli, J. K. Jørgensen, E. A. Bergin +9

How protostars accrete mass is one of the fundamental problems of star formation. High column densities and complex kinematical structures make direct observations challenging and…

Probing the effects of external irradiation on low-mass protostars through unbiased line surveys

Johan E. Lindberg, Jes K. Jørgensen, Yoshimasa Watanabe +3

(abridged) Context: The envelopes of molecular gas around embedded low-mass protostars show different chemistries, which can be used to trace their formation history and physical c…

A Substellar-Mass Protostar and its Outflow of IRAS 15398-3359 Revealed by Subarcsecond-Resolution Observations of HCO and CCH

Yoko Oya, Nami Sakai, Takeshi Sakai +7

Sub-arcsecond () images of HCO and CCH line emission have been obtained in the mm band toward the low-mass protostar IRAS 15398-3359 in the Lupus 1 cl…

ALMA observations of the kinematics and chemistry of disc formation

Johan E. Lindberg, Jes K. Jørgensen, Christian Brinch +6

Context: The R CrA cloud hosts a handful of Class 0/I low-mass young stellar objects. The chemistry and physics at scales AU in this cloud are dominated by the irradiation f…

A recent accretion burst in the low-mass protostar IRAS 15398-3359: ALMA imaging of its related chemistry

Jes K. Jorgensen, Ruud Visser, Nami Sakai +8

Low-mass protostars have been suggested to show highly variable accretion rates through-out their evolution. Such changes in accretion, and related heating of their ambient envelop…

Warm gas towards young stellar objects in Corona Australis - Herschel/PACS observations from the DIGIT key programme

Johan E. Lindberg, Jes K. Jørgensen, Joel D. Green +5

The effects of external irradiation on the chemistry and physics in the protostellar envelope around low-mass young stellar objects are poorly understood. The Corona Australis star…

Strong irradiation of protostellar cores in Corona Australis

J. E. Lindberg, J. K. Jørgensen

The importance of the physical environment in the evolution of newly formed low-mass stars remains an open question. In particular, radiation from nearby more massive stars may aff…
