Planets are formed inside disks around young stars. The gas, dust, and ice in these natal
disks are the building materials of planets, and therefore, their compositions fundamentally …

Accurate parameters of molecular hot-band transitions, ie, those starting from vibrationally
excited levels, are needed to accurately model high-temperature spectra in astrophysics and …

Context. Complex organic molecules (COMs) are ubiquitously detected in the gas phase
and thought to be mostly formed on icy grains. Nevertheless, there have not been any …

Context. JWST has taken the sharpest and most sensitive infrared (IR) spectral imaging
observations ever of the Orion Bar photodis-sociation region (PDR), which is part of the …

Most low-mass stars form in stellar clusters that also contain massive stars, which are
sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiation …

Context. The methyl cation (CH 3+) has recently been discovered in the interstellar medium
through the detection of 7 μm (1400 cm− 1) features toward the d203-506 protoplanetary …

The gas-phase abundance of carbon, x C=[C/H] gas= x C++ x C 0+ x CO+…, and its
depletion factors are essential parameters for understanding the gas and solid compositions …

The study of protoplanetary disks has become increasingly important with the Kepler
satellite finding that exoplanets are ubiquitous around stars in our galaxy and the discovery …

Quantum chemical cluster calculations employing density functional theory and correlation
consistent basis sets reveal the following pathways by which hydroxide anions (OH–) may …

In various astronomical environments such as the interstellar medium or (exo) planetary
atmospheres, an interplay of bottom-up growth and top-down destruction processes of …
