New Insights Into The Potential For Life In The Jovian System
Southwest Research Institute was part of an international team that demonstrated how complex organic molecules (COMs), key chemical precursors to life, could have been incorporated into Jupiter’s Galilean moons during […]
Observational Signatures Of Circumstellar Gas Tori Formed by Planetary Mass-Loss from Close-In Exoplanets
Close-in exoplanets with H/He atmospheres often undergo hydrodynamic escape. In extreme cases, it is hypothesized that the mass loss can be high enough for the escaping planetary material to wrap […]
Delivery Of Complex Organic Molecules To The System Of Jupiter
Complex organic molecules are key markers of molecular diversity, and their formation conditions in protoplanetary disks remain an active area of research. These molecules have been detected on a variety […]
Interstellar Formation of Thioethanal (CH3CHS). Gas-Phase and Ice-Surface Mechanisms involving Secondary Sulfur Products
The formation pathways of sulfur-bearing species in the interstellar medium are crucial to understand astrochemical processes in cold molecular clouds and to gain new insights about the sulfur budget in […]
Formation and Survival of Complex Organic Molecules in the Jovian Circumplanetary Disk
Europa, Ganymede, and Callisto are key targets in the search for habitability due to the potential presence of subsurface oceans. Detecting complex organic molecules (COMs), essential for prebiotic chemistry, is […]
Infrared Spectra Of Methane-containing Ice Mixtures For JWST Data Analysis
Context. Solid methane (CH4) is an important molecule in interstellar and planetary environments, serving as a precursor to complex organic compounds and a potential biosignature in exoplanetary studies. Despite its […]
Bennu And Ryugu Cconstituents From Samples IR Analyses And Potential Source Of Terrestrial Planets’ Ingredients
Samples collected on carbonaceous asteroids and preserved from terrestrial alteration are key witnesses of the early evolution of the Solar System. Here we present the results of the characterization, by […]
Machine Learning Exploration Of Binding Energy Distributions Of H2O At Astrochemically Relevant Dust Grain Surfaces
Binding energies (BEs) of adsorbates on interstellar dust grains critically control adsorption, desorption, diffusion, and surface reactivity, and therefore strongly influence astrochemical models of star- and planet-forming regions.
Organic Acid Chemistry in ISM: Detection of Formic Acid and its Prebiotic Chemistry in Hot Core G358.93−0.03 MM1
In the interstellar medium, formic acid (HCOOH) plays a significant role in the synthesis of the simplest amino acid, glycine (NH2CH2COOH). The presence of HCOOH suggests that oxygen-bearing molecules may […]
