Dual Effects of Ram Pressure on Star Formation in Multiphase Disk Galaxies with Strong Stellar Feedback [PDF]

Astrophysical Journal, 2020
We investigate the impact of ram pressure stripping due to the intracluster medium (ICM) on star-forming disk galaxies with a multiphase interstellar medium maintained by strong stellar feedback.

Pre-supernova stellar feedback in nearby starburst dwarf galaxies [PDF]

Astronomy & Astrophysics
Stellar feedback in dwarf galaxies remains, to date, poorly explored, yet is crucial to understanding galaxy evolution in the early Universe. In particular, pre-supernova feedback has recently been found to play a significant role in regulating and ...

Influence of surface stressing on stellar coronae and winds [PDF]

, 2013
STFC funding has supported this research.The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-scale surface magnetic fields that ...

Application of Convolutional Neural Networks to Identify Stellar Feedback Bubbles in CO Emission [PDF]

Astrophysical Journal, 2020
We adopt the deep learning method called the Convolutional Approach to Shell Identification (casi) and extend it to 3D (casi-3d) to identify signatures of stellar feedback in molecular line spectra.

Interplay of stellar and gas-phase metallicities: unveiling insights for stellar feedback modeling with illustris, IllustrisTNG, and EAGLE [PDF]

Monthly notices of the Royal Astronomical Society
The metal content of galaxies provides a window into their formation in the full context of the cosmic baryon cycle. In this study, we examine the relationship between stellar mass and stellar metallicity (MZ*R) in the hydrodynamic simulations ...

FEEDBACK: a SOFIA Legacy Program to Study Stellar Feedback in Regions of Massive Star Formation [PDF]

Publications of the Astronomical Society of the Pacific, 2020
FEEDBACK is a SOFIA (Stratospheric Observatory for Infrared Astronomy) legacy program dedicated to study the interaction of massive stars with their environment.

Stellar evolution and feedback connections to stellar dynamics [PDF]

Proceedings of the International Astronomical Union, 2006
AbstractUntil a few years ago, the common paradigm for the formation of Globular Clusters (GCs) was that they constitute a ‘simple stellar population’ in which all the stars were formed from a chemically homogeneous cluster medium within a relatively short interval of time, at the beginning of the galactic life.

Stellar dynamics and feedback connections to stellar evolution [PDF]

Proceedings of the International Astronomical Union, 2006
AbstractIn dense stellar systems, dynamical interactions between objects inevitably lead to frequent formation of exotic stellar objects and multiple systems, thereby imposing new questions for the stellar evolution theory. The evolutionary path of such systems could be different from that of the unperturbed objects, therefore, we must re-evaluate ...

Simulating the interstellar medium and stellar feedback on a moving mesh: implementation and isolated galaxies [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We introduce the Stars and MUltiphase Gas in GaLaxiEs – SMUGGLE model, an explicit and comprehensive stellar feedback model for the moving-mesh code arepo. This novel sub-resolution model resolves the multiphase gas structure of the interstellar medium
