On the formation of cores in accreting filaments and the impact of ambient environment on it
S. V. Anathpindika, J. Di Francesco
Recent numerical works, including ours, lend credence to the thesis that ambient environment, i.e., external pressure, affects star-forming ability of clouds & filaments. In contin…
Core formation via filament fragmentation and the impact of ambient pressure on it
S. Anathpindika, J. Di Francesco
Prestellar cores are generally spheroidal, some of which appear oblate while others appear prolate. Very few of them appear circular in projection. Little, however, is understood a…
On filament fragmentation and the impact of ambient environment on it
S. Anathpindika, J. Di Francesco
Filaments are crucial intermediaries in the star formation process. Recent observations of filaments show that - \textbf{(i)} a number of them are non-singular entities, and rather…
On the star-forming ability of Molecular Clouds
S. Anathpindika, A. Burkert, R. Kuiper
The star-forming ability of a molecular cloud depends on the fraction of gas it can cycle into the dense-phase. Consequently, one of the crucial questions in reconciling star-forma…
On the impact of the magnitude of Interstellar pressure on physical properties of Molecular Cloud
S. Anathpindika, A. Burkert, R. Kuiper
Recently reported variations in the typical physical properties of Galactic and extra-Galactic molecular clouds (MCs), and in their ability to form stars have been attributed to lo…
Why do some cores remain starless ?
S. Anathpindika
Physical conditions that could render a core starless(in the local Universe) is the subject of investigation in this work. To this end we studied the evolution of four starless cor…
Stability of filaments in star-forming clouds and the formation of prestellar cores in them
S. Anathpindika, J. Freundlich
It is now widely accepted that dense filaments of molecular gas are integral to the process of stellar birth. While numerical simulations have succeeded in reproducing filamentary…
Formation of prestellar cores via non-isothermal gas fragmentation
S. Anathpindika
Sheet-like clouds are common in turbulent gas and perhaps form via collisions between turbulent gas flows. Having examined the evolution of an isothermal shocked slab in an earlier…
Does a prestellar core always become protostellar? Tracing the evolution of cores from the prestellar to protostellar phase
S. Anathpindika, James Di Francesco
Recently, a subset of starless cores whose thermal Jeans mass is apparently overwhelmed by the mass of the core has been identified, e.g., the core {\small L183}. In literature, ma…
On the evolution of irradiated turbulent clouds: A comparative study between modes of triggered star-formation
S. Anathpindika, H. C. Bhatt
Here we examine the evolution of irradiated clouds using the Smoothed Particle Hydrodynamics ({\small SPH}) algorithm coupled with a ray-tracing scheme that calculates the position…
On turbulent fragmentation and the origin of the stellar IMF
S. Anathpindika
Two varieties of the universal stellar initial mass function (IMF) viz., the Kroupa and the Chabrier IMF, have emerged over the last decade to explain the observed distribution of…
The contagion of star-formation: Its origin
S. Anathpindika
Dense pockets of cold, molecular gas precede the formation of stars. During their infancy and later phases of evolution, stars inject considerable energy into the interstellar medi…
India's tryst with modern astronomy
S. Anathpindika
Sumedh Anathpindika surveys astronomy in India and finds a lively and developing community as well as great public interest.
The CMF as provenance of the stellar IMF ?
S. Anathpindika
In the present work we examined the hypothesis that, a core mass function (CMF), such as the one deduced for cores in the Orion molecular cloud (OMC), could possibly be the primoge…
On the propensity of the formation of massive clumps via fragmentation of driven shells
S. Anathpindika
Early type massive stars drive thin, dense shells whose edges often show evidence of star-formation. The possibility of fragmentation of these shells, leading to the formation of p…
On the interaction of a thin, supersonic shell with a molecular cloud
S. Anathpindika, H. C. Bhatt
Molecular clouds (MCs) are stellar nurseries, however, formation of stars within MCs depends on the ambient physical conditions. MCs, over a free-fall time are exposed to numerous…
Supersonic Cloud Collision-II
S. V. Anathpindika
In this second paper of the sequel of two papers, we further investigate the problem of molecular cloud (MC) collision. Anathpindika (2009) (hereafter paper I) considered highly su…
Supersonic Cloud Collision - I
S. V. Anathpindika
It has long been suggested that shocks might play an important role in altering the form of the interstellar medium (ISM). Shocks enhance gas density and sufficiently dense regions…
The direction of outflows from filaments : constraints on core formation
S. V. Anathpindika, A. P. Whitworth
Context: It is generally presumed that the outflows from a YSO are directed close to its rotation axis (i.e. along its angular momentum vector and orthogonal to any attendant accre…
