Assessing the accuracy of the star formation rate measurements by direct star count in molecular clouds
Sami Dib, Jian Wen Zhou, Sébastien Comerón +8
Star formation estimates based on the counting of YSOs is commonly applied to nearby star-forming regions in the Galaxy. With this method, the SFRs are measured using the counts of…
The structure and characteristic scales of molecular clouds
Sami Dib, Sylvain Bontemps, Nicola Schneider +8
The structure of molecular clouds (MCs) holds important clues on the physical processes that lead to their formation and subsequent evolution. While it is well established that tur…
Time-dependent evolution of the protoplanetary discs with magnetic winds
Mohsen Shadmehri, Sayyedeh Masoumeh Ghoreyshi
We study the evolution of the protoplanetary discs (PPDs) in the presence of magnetically driven winds with the stress relations motivated by the non-ideal MHD disc simulations. Co…
Linear Analysis of the Nonaxisymmetric Secular Gravitational Instability
Mohsen Shadmehri, Razieh Oudi, Gohar Rastegarzadeh
In protoplanetary discs (PPDs) consisting of gas and dust particles, fluid instabilities induced by the drag force, including secular gravitational instability (SGI) can facilitate…
Properties of an accretion disc with a power-law stress-pressure relationship
Mohsen Shadmehri, Fazeleh Khajenabi, Sami Dib +1
Recent numerical simulations of magnetized accretion discs show that the radial-azimuthal component of the stress tensor due to the magnetorotational instability (MRI) is well repr…
Evolution of circumbinary protoplanetary disks with photoevaporative winds driven by External Far Ultraviolet Radiation
Mohsen Shadmehri, S. M. Ghoreyshi, N. Alipour
Lifetimes of protoplanetary disks (PPDs) are believed to be severely constrained by material depleting mechanisms, including photoevaporative winds due to the host star radiation o…
