Dust-driven vortex cascades originating at water snow regions: A pathway to planetesimal formation
Kundan Kadam, Zsolt Regály
The origin of observed planetary systems, including our Solar System, as well as their diversity, is still an open question. Streaming instability (SI) is an important mechanism fo…
Dust in the wind of outbursting young stars
Kundan Kadam, Eduard Vorobyov, Peter Woitke +1
Context. Young Stellar Objects (YSOs) are observed to undergo powerful accretion events known as FU Orionis outbursts (FUors). Such events of episodic accretion are now considered…
Magnetic disk winds in protoplanetary disks: Description of the model and impact on global disk evolution
Kundan Kadam, Eduard Vorobyov, Peter Woitke +2
Canonically, a protoplanetary disk is thought to undergo (gravito-)viscous evolution, wherein the angular momentum of the accreting material is transported outwards. However, sever…
CAI formation in the early Solar System
P. Woitke, J. Drażkowska, H. Lammer +2
Ca-Al-rich inclusions (CAIs) are the oldest dated solid materials in the solar system, found as light-coloured crystalline ingredients in meteorites. Their formation time is common…
Planetary nurseries: vortices formed at smooth viscosity transition
Zs. Regaly, K. Kadam, D. Tarczay-Nehez
Excitation of Rossby wave instability and development of a large-scale vortex at the outer dead zone edge of protoplanetary discs is one of the leading theories that explains horse…
Primordial Dusty Rings and Episodic Outbursts in Protoplanetary Discs
Kundan Kadam, Eduard Vorobyov, Shantanu Basu
We investigate the formation and evolution of "primordial" dusty rings occurring in the inner regions of protoplanetary discs, with the help of long-term, coupled dust-gas, magneto…
Synthetic Polarization Maps of an Outflow Zone from Magnetohydrodynamic Simulations
Gianfranco Bino, Shantanu Basu, Masahiro N Machida +4
The canonical theory of star formation in a magnetized environment predicts the formation of hourglass-shaped magnetic fields during the prestellar collapse phase. In protostellar…
Jupiter as a Rotating Bipolytrope
Kundan Kadam
Polytropes have long been used to model a wide variety of astrophysical objects. A bipolytrope (composite polytrope) may be used for bodies with a distinct core-envelope structure.…
Self-Sustaining Vortices in Protoplanetary Disks: Setting the Stage for Planetary System Formation
Zsolt Regaly, Kundan Kadam, Cornelis P. Dullemond
The core accretion scenario of planet formation assumes that planetesimals and planetary embryos are formed during the primordial, gaseous phases of the protoplanetary disk. Howeve…
Eruptive Behavior of Magnetically Layered Protoplanetary Disks in Low Metallicity Environments
Kundan Kadam, Eduard Vorobyov, Ágnes Kóspál
A protoplanetary disk typically forms a dead zone near its midplane at the distance of a few au from the central protostar. Accretion through such a magnetically layered disk can b…
Global Protoplanetary Disk Simulations: Dead Zone Formation and FUor Outbursts
Kundan Kadam, Eduard Vorobyov, Zsolt Regály +2
We conducted global hydrodynamic simulations of protoplanetary disk evolution with an adaptive Shakura-Sunyaev α prescription to represent the layered disk structure, and starting…
ALMA and VLA Observations of EX Lupi in its Quiescent State
Jacob Aaron White, Á. Kóspál, A. G. Hughes +15
Extreme outbursts in young stars may be a common stage of pre-main-sequence stellar evolution. These outbursts, caused by enhanced accretion and accompanied by increased luminosity…
Outbursts in Global Protoplanetary Disk Simulations
Kundan Kadam, Eduard Vorobyov, Zsolt Regály +2
While accreting through a circumstellar disk, young stellar objects are observed to undergo sudden and powerful accretion events known as FUor or EXor outbursts. Although such epis…
Dynamical Gaseous Rings in Global Simulations of Protoplanetary Disk Formation
Kundan Kadam, Eduard Vorobyov, Zsolt Regály +2
Global numerical simulations of protoplanetary disk formation and evolution were conducted in thin-disk limit, where the model included magnetically layered disk structure, a self-…
Science with an ngVLA: Resolving the Radio Complexity of EXor and FUor-type Systems with the ngVLA
Jacob Aaron White, Marc Audard, Péter Ábrahám +17
Episodic accretion may be a common occurrence in the evolution of young pre-main sequence stars and has important implications for our understanding of star and planet formation. M…
Numerical Simulations of Mass Transfer in Binaries with Bipolytropic Components
Kundan Kadam, Patrick M. Motl, Dominic C. Marcello +2
We present the first self-consistent, three dimensional study of hydrodynamic simulations of mass transfer in binary systems with bipolytropic (composite polytropic) components. In…
A Numerical Method for Generating Rapidly Rotating Bipolytropic Structures in Equilibrium
Kundan Kadam, Patrick M. Motl, Juhan Frank +2
We demonstrate that rapidly rotating bipolytropic (composite polytropic) stars and toroidal disks can be obtained using Hachisu's self consistent field technique. The core and the…
