Stellar feedback efficiencies: supernovae versus stellar winds [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 Stellar winds and supernova (SN) explosions of massive stars ('stellar feedback') create bubbles in the interstellar medium (ISM) and insert newly produced heavy elements and kinetic energy into their surroundings, possibly driving turbulence.

Stellar feedback in a clumpy galaxy at z ∼ 3.4 [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 Giant star-forming regions (clumps) are widespread features of galaxies at z ≈ 1−4. Theory predicts that they can play a crucial role in galaxy evolution, if they survive to stellar feedback for >50 Myr. Numerical simulations show that clumps’ survival

Stellar Multiplicity in an RMHD Simulation with Stellar Feedback
Research Notes of the AAS, 2021 Unlike the Sun, most observed stars are part of a multiple star system, but the formation of such systems is still not well understood. To study this problem, we utilize a run from the STARFORGE simulation suite that simulates the evolution of star ...

Evolution of Stellar Feedback in H ii Regions [PDF]
The Astrophysical Journal, 2020 Stellar feedback is needed to produce realistic giant molecular clouds and galaxies in simulations, but due to limited numerical resolution, feedback must be implemented using sub-grid models.

Kinematics of Young Stellar Objects under Various Stellar Feedback
The Astrophysical Journal Supplement SeriesBased on the Gaia Data Release 3 and APOGEE data sets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby star-forming regions.

The maximum stellar surface density due to the failure of stellar feedback [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 A maximum stellar surface density Σ_(max) ∼ 3×10^5M⊙ pc^(−2) is observed across all classes of dense stellar systems (e.g. star clusters, galactic nuclei, etc.), spanning ∼8 orders of magnitude in mass. It has been proposed that this characteristic scale

Stellar Feedback and Resolved Stellar IFU Spectroscopy in the Nearby Spiral Galaxy NGC 300 [PDF]
The Astrophysical Journal, 2019 We present MUSE integral field unit (IFU) observations of five individual H ii regions in two giant star-forming complexes in the low-metallicity, nearby dwarf spiral galaxy NGC 300.

Stellar Feedback, AGN Feedback and Fluid Microphysics in Galaxy Evolution [PDF]
, 2019 Understanding how the baryonic physics affects the formation and evolution of galaxies is one of the most critical questions in modern astronomy. Significant progress in understanding stellar feedback and modeling them explicitly in simulations have made
