Numerical modeling of gravitational instability outcomes in multiphase circumstellar discs

EPJ Web of Conferences, 2013
To suggest consistent route toward planetesimal and planetary core formation in circumstellar discs we study gravitational instability outcomes in massive multiphase (gas-collisionless bodies) disc.

The Extent of Solar Energetic Particle Irradiation in the Sun’s Protoplanetary Disk

The Astrophysical Journal
Solar flares emit X-rays and high-energy (MeV to GeV) ions called solar energetic particles (SEPs). Astronomical observations show solar-mass protostellar fluxes are a factor Φ ≈ 3 × 10 ^2 –3 × 10 ^3 times higher than the present-day Sun.

CORINOS. II. JWST-MIRI Detection of Warm Molecular Gas from an Embedded, Disk-bearing Protostar

The Astrophysical Journal
We present James Webb Space Telescope (JWST) Mid-InfraRed Instrument (MIRI) observations of warm CO and H _2 O gas in emission toward the low-mass protostar IRAS 15398-3359, observed as part of the CORINOS program.
