Understanding the interaction between hydrogen cyanide (HCN) and silicate surfaces is crucial for elucidating the prebiotic processes occurring on interstellar grain cores, as well as in cometary and meteoritic matrices.
Despite its biogeneic and astrochemical importance, sulfur (S), the 10th most abundant element in the interstellar medium (ISM) with a total abundance of S/H~2.2E-5, largely remains undetected in molecular clouds.
NEMESISPY is a Python package developed to perform parametric atmospheric modelling and radiative transfer calculation for the retrievals of exoplanetary spectra.
We present an atmospheric retrieval analysis of the Y0 brown dwarf WISE J035934.06−540154.6 using the low-resolution 0.96–12 μm JWST spectrum presented in Beiler_2023. We obtain volume number mixing ratios of […]
Astronomers have proposed a new theory to explain the origin of phosphorus, one of the elements important for life on Earth. The theory suggests a type of stellar explosion known […]
The relationship between stars and planets provides important information for understanding the interior composition, mineralogy, and overall classification of small planets (R ≲ 3.5R⊕).
Life is indeed possible on Earth. This has been demonstrated in a study conducted by the Institute of Particle Physics and Astrophysics at ETH Zurich. Of course, the researchers’ intention […]
