Variable accretion in young stellar objects reveals itself photometrically and
spectroscopically over a continuum of timescales and amplitudes. Most dramatic are the …

Context. The physical and chemical conditions in Class 0/I protostars are fundamental in
unlocking the protostellar accretion process and its impact on planet formation. Aims. The …

Astrochemistry is the science that studies the chemistry in the Universe, namely the
combination of two fields: astronomy and chemistry. It started about fifty years ago and it has …

Context. Complex organic molecules (COMs), especially the oxygen-bearing species, have
been observed to be abundant in the gas phase toward low-mass and high-mass protostars …

Context. The Mid-InfraRed Instrument (MIRI) on board the James Webb Space Telescope
(JWST) allows one to probe the molecular gas composition at mid-infrared (mid-IR) …

Characterizing the physical conditions at disk scales in class 0 sources is crucial for
constraining the protostellar accretion process and the initial conditions for planet formation …

The huge variety of planetary systems discovered in recent decades likely depends on the
early history of their formation. In this contribution, we introduce the FAUST Large Program …

Methyl cyanide (CH3CN) is one of the most abundant and widely spread interstellar
complex organic molecules (iCOMs). Several studies found that, in hot corinos, methyl …

The presence of complex organic molecules (COMs) in the interstellar medium is of great
interest since it may link to the origin and prevalence of life in the universe. Aiming to …

Episodic accretion in protostars leads to luminosity outbursts that end up heating their
surroundings. This rise in temperature pushes the snow lines back, enabling the desorption …
