Critical Condition of Core-collapse Supernovae. I. One-dimensional Models

The Astrophysical Journal
When the core of a massive star collapses, neutrino heating can energize the stalled accretion shock, leading to a successful supernova. The critical condition that characterizes the transition from accretion to explosion is a central topic of study and ...

High accuracy power spectra including baryonic physics in dynamical Dark Energy models

, 2010
The next generation mass probes will obtain information on non--linear power spectra P(k,z) and their evolution, allowing us to investigate the nature of Dark Energy.

From Common Envelope Evolution to Luminous Red Novae. I. A One-dimensional Radiation Hydrodynamic Model

The Astrophysical Journal
The acceleration and unbinding of the common envelope during the plunge-in phase are governed by complex physical processes that often manifest observationally as luminous red novae.

Origin and evolution of magnetic fields in PMS stars : influence of rotation and structural changes

, 2017
During stellar evolution, especially in the PMS, stellar structure and rotation evolve significantly causing major changes in the dynamics and global flows of the star.

Mass Ejection Driven by Sudden Energy Deposition in Stellar Envelopes

The Astrophysical Journal
A number of stellar astrophysical phenomena, such as tidal novae and planetary engulfment, involve sudden injection of subbinding energy in a thin layer within the star, leading to mass ejection of the stellar envelope.

The AGORA High-resolution Galaxy Simulations Comparison Project. V. Satellite Galaxy Populations in a Cosmological Zoom-in Simulation of a Milky Way–Mass Halo

The Astrophysical Journal
We analyze and compare the satellite halo populations at z ∼ 2 in the high-resolution cosmological zoom-in simulations of a 10 ^12 M _⊙ target halo ( z = 0 mass) carried out on eight widely used astrophysical simulation codes ( Art-I , Enzo , Ramses ...

Disk-planets interactions and the diversity of period ratios in Kepler's multi-planetary systems

, 2013
The Kepler mission is dramatically increasing the number of planets known in multi-planetary systems. Many adjacent planets have orbital period ratios near resonant values, with a tendency to be larger than required for exact first-order mean-motion ...

The AGORA High-resolution Galaxy Simulations Comparison Project. VI. Similarities and Differences in the Circumgalactic Medium

The Astrophysical Journal
We analyze the circumgalactic medium (CGM) for eight commonly-used cosmological codes in the AGORA collaboration. The codes are calibrated to use identical initial conditions, cosmology, heating and cooling, and star formation thresholds, but each ...

Impact of Self-shielding Minihalos on the Lyα Forest at High Redshift

The Astrophysical Journal
Dense gas in minihalos with masses of 10 ^6 −10 ^8 M _⊙ can shield themselves from reionization for ∼100 Myr after being exposed to the UV background.
