The Mass Evolution of Protostellar Disks and Envelopes in the Perseus Molecular Cloud

Bridget C. Andersen, Ian W. Stephens, Michael M. Dunham +8

In the standard picture for low-mass star formation, a dense molecular cloud undergoes gravitational collapse to form a protostellar system consisting of a new central star, a circ…

Chemistry of a newly detected circumbinary disk in Ophiuchus

E. Artur de la Villarmois, L. E. Kristensen, J. K. Jørgensen +6

(Abridged) Astronomers recently started discovering exoplanets around binary systems. Therefore, understanding the formation and evolution of circumbinary disks is crucial for a co…

Episodic accretion: the interplay of infall and disc instabilities

Michael Kuffmeier, Søren Frimann, Sigurd S. Jensen +1

Using zoom-simulations carried out with the adaptive mesh-refinement code RAMSES with a dynamic range of up to we investigate the accretion profil…

Supernova Driving. IV. The Star Formation Rate of Molecular Clouds

Paolo Padoan, Troels Haugbølle, Åke Nordlund +1

We compute the star formation rate (SFR) in molecular clouds (MCs) that originate {\it ab initio} in a new, higher-resolution simulation of supernova-driven turbulence. Because of…

Protostellar accretion traced with chemistry. High resolution C18O and continuum observations towards deeply embedded protostars in Perseus

Søren Frimann, Jes K. Jørgensen, Michael M. Dunham +6

Context: Understanding how accretion proceeds is a key question of star formation, with important implications for both the physical and chemical evolution of young stellar objects…

The Astropy Problem

Demitri Muna, Michael Alexander, Alice Allen +151

The Astropy Project (http://astropy.org) is, in its own words, "a community effort to develop a single core package for Astronomy in Python and foster interoperability between Pyth…

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…

Protostellar accretion traced with chemistry: Comparing synthetic C18O maps of embedded protostars to real observations

Søren Frimann, Jes K. Jørgensen, Paolo Padoan +1

Context: Understanding how protostars accrete their mass is a central question of star formation. One aspect of this is trying to understand whether the time evolution of accretion…

Large-scale numerical simulations of star formation put to the test: Comparing synthetic images and actual observations for statistical samples of protostars

Søren Frimann, Jes K. Jørgensen, Troels Haugbølle

(abridged) Context: Both observations and simulations of embedded protostars have progressed rapidly in recent years. Bringing them together is an important step in advancing our k…

Sounding stellar cycles with Kepler - II. Ground-based observations

C. Karoff, T. S. Metcalfe, W. J. Chaplin +11

We have monitored 20 Sun-like stars in the Kepler field-of-view for excess flux with the FIES spectrograph on the Nordic Optical Telescope since the launch of Kepler spacecraft in…

The first evidence for multiple pulsation axes: a new roAp star in the Kepler field, KIC 10195926

D. W. Kurtz, M. S. Cunha, H. Saio +14

We have discovered a new rapidly oscillating Ap star among the Kepler Mission target stars, KIC 10195926. This star shows two pulsation modes with periods that are amongst the long…
