Cold Dark Clouds: The Initial Conditions for Star Formation
AbstractCold dark clouds are nearby members of the densest and coldest phase in the Galactic interstellar medium, and represent the most accessible sites where stars like our Sun are currently being… Expand
WATER, O2, AND ICE IN MOLECULAR CLOUDS
We model the temperature and chemical structure of molecular clouds as a function of depth into the cloud, assuming a cloud of constant density n illuminated by an external far-ultraviolet (FUV; 6 eV… Expand
An old disk still capable of forming a planetary system
TLDR
The detection of hydrogen deuteride, combined with existing observations and detailed models, implies a disk mass of more than 0.05 solar masses, which is enough to form a planetary system like the authors' own. Expand
The Effects of Snowlines on C/O in Planetary Atmospheres
The C/O ratio is predicted to regulate the atmospheric chemistry in hot Jupiters. Recent observations suggest that some exoplanets, e.g., Wasp 12-b, have atmospheric C/O ratios substantially… Expand
Ocean-like water in the Jupiter-family comet 103P/Hartley 2
TLDR
It is reported that the D/H ratio in the Jupiter-family comet 103P/Hartley 2, which originated in the Kuiper belt, is (1.61 ± 0.24) × 10−4, which substantially expands the reservoir of Earth ocean-like water to include some comets, and is consistent with the emerging picture of a complex dynamical evolution of the early Solar System.

A Uniform Catalog of Molecular Clouds in the Milky Way
The all-Galaxy CO survey of Dame, Hartmann, & Thaddeus (2001) is by far the most uniform, large-scale Galactic CO survey. Using a dendrogram-based decomposition of this survey, we present a catalog… Expand
A study of the physics and chemistry of TMC-1.
TLDR
The most striking abundance variations relative to HCO+ along the ridge were seen for HC3N, CH3CCH, and SO, while smaller variations were seen in CS, C2H, and HCN, indicating that the so-called NH3 peak in TMC-1 is probably a peak in the ammonia column density rather than a relative abundance peak.

Detection of the Water Reservoir in a Forming Planetary System
TLDR
The Heterodyne Instrument for the Far-Infrared on board the Herschel Space Observatory has detected emission lines from both spin isomers of cold water vapor from the disk around the young star TW Hydrae, hinting at a water ice reservoir equivalent to several thousand Earth oceans in mass. Expand
Rapid Formation of Molecular Clouds and Stars in the Solar Neighborhood
We show how molecular clouds in the solar neighborhood might be formed and produce stars rapidly enough to explain stellar population ages, building on results from numerical simulations of the… Expand
Chemical Evolution in Preprotostellar and Protostellar Cores
The chemistry of developing and collapsing low-mass protostellar cores is followed using a chemical code with a time-varying density. Two evolutionary scenarios are represented, gravitational… Expand
