Theoretical Water Binding Energy Distribution and Snowline in Protoplanetary Disks
The Astrophysical Journal, 2023 Water is one of the most important and abundant molecules in star-forming regions. In protoplanetary disks, where planets and comets form, H _2 O is in a gas or solid form, depending on the dust temperature, i.e., the distance from the center and its ...

On the Spatial Distribution of 13CO Structures within 12CO Molecular Clouds
The Astrophysical Journal, 2023 We look into the 2851 ^12 CO molecular clouds harboring ^13 CO structures to reveal the distribution of the projected angular separations and radial velocity separations between their internal ^13 CO structures.

Broadband VLA Spectral-line Survey of a Sample of Ionized Jet Candidates
The Astrophysical Journal Supplement Series, 2023 The study of the interaction between ionized jets, molecular outflows, and their environments is critical to understanding high-mass star formation, especially because jets and outflows are thought to be key in the transfer of angular momentum outward ...

Dust evolution, a global view: II. Top-down branching, nanoparticle fragmentation and the mystery of the diffuse interstellar band carriers [PDF]
Royal Society Open Science, 2016 The origin of the diffuse interstellar bands (DIBs), one of the longest-standing mysteries of the interstellar medium (ISM), is explored within the framework of The Heterogeneous dust Evolution Model for Interstellar Solids (THEMIS). The likely nature of

Photoabsorption and photodissociation of molecules important in the interstellar medium [PDF]
The photo absorption, photo dissociation, and fluorescence cross sections of interstellar molecules and radicals were measured in the vacuum ultraviolet region. These quantitative optical data are useful for understanding of the formation and destruction
