Planets form in disks of gas and dust around young stars. The disk molecular reservoirs and
their chemical evolution affect all aspects of planet formation, from the coagulation of dust …

Flattened, rotating disks of cool dust and gas extending for tens to hundreds of astronomical
units are found around almost all low-mass stars shortly after their birth. These disks …

To date, 204 individual molecular species, comprised of 16 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

Context. Water is a key molecule in the physics and chemistry of star and planet formation,
but it is difficult to observe from Earth. The Herschel Space Observatory provided …

To date, 241 individual molecular species, composed of 19 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

We present a sensitive, multiwavelength submillimeter continuum survey of 153 young
stellar objects in the Taurus-Auriga star formation region. The submillimeter detection rate is …

Aims. Photodissociation by UV light is an important destruction mechanism for carbon
monoxide (CO) in many astrophysical environments, ranging from interstellar clouds to …

The concentric gaps and rings commonly observed in protoplanetary disks in millimeter
continuum emission have lent the impression that planet formation generally proceeds …

Context. Emission lines from protoplanetary disks originate mainly in the irradiated surface
layers, where the gas is generally warmer than the dust. Therefore, interpreting emission …

We present a high spatial resolution submillimeter continuum survey of 24 circumstellar
disks in the Taurus-Auriga and Ophiuchus-Scorpius star formation regions using the SMA. In …
