Carbon-Oxygen Phase Separation in Modules for Experiments in Stellar Astrophysics (MESA) White Dwarf Models

期刊: ASTROPHYSICAL JOURNAL, 2023; 950 (2)

We enhance the treatment of crystallization for models of white dwarfs (WDs) in the stellar evolution software Modules for Experiments in Stellar Astr......

Neutron Star Phase Transition as the Origin for the Fast Radio Bursts and Soft Gamma-Ray Repeaters of SGR J1935+2154

期刊: ASTROPHYSICAL JOURNAL, 2023; 951 (1)

Magnetars are believed to be neutron stars (NSs) with strong magnetic fields. X-ray flares and fast radio bursts (FRBs) have been observed from the ma......

HALO7D. III. Chemical Abundances of Milky Way Halo Stars from Medium-resolution Spectra

期刊: ASTROPHYSICAL JOURNAL, 2023; 951 (1)

The Halo Assembly in Lambda Cold Dark Matter: Observations in 7 Dimensions (HALO7D) survey measures the kinematics and chemical properties of stars in......

On the Origin of Radio-loudness in Active Galactic Nuclei Using Far-infrared Polarimetric Observations

期刊: ASTROPHYSICAL JOURNAL, 2023; 951 (1)

The dichotomy between radio-loud (RL) and radio-quiet (RQ) active galactic nuclei (AGNs) is thought to be intrinsically related to radio jet productio......

Theoretical Light-curve Models of the Symbiotic Nova CN Cha-Optical Flat Peak for 3 Yr

期刊: ASTROPHYSICAL JOURNAL, 2023; 951 (2)

CN Cha is a slow symbiotic nova characterized by a 3 yr long optical flat peak followed by a rapid decline. We present theoretical light curves for CN......

ALMA 1.1 mm Observations of a Conservative Sample of High-redshift Massive Quiescent Galaxies in SHELA

期刊: ASTROPHYSICAL JOURNAL, 2023; 951 (1)

We present a sample of 30 massive (log(M (*)/M (& ODOT;)) > 11) z = 3-5 quiescent galaxies selected from the Spitzer-HETDEX Exploratory Large A......

On the Formation of Vinylamine (C2H3NH2) in Interstellar Ice Analogs

期刊: ASTROPHYSICAL JOURNAL, 2023; 952 (2)

Amines-organic molecules carrying the -NH2 moiety-have been recognized as a vital intermediate in the formation of prebiotic molecules such as amino a......

A Spectral-timing Study of the Inner Flow Geometry in MAXI J1535-571 with Insight-HXMT and NICER

期刊: ASTROPHYSICAL JOURNAL, 2023; 953 (2)

We have performed a spectral-timing analysis of the black hole X-ray binary MAXI J1535-571 during its 2017 outburst, with the aim of exploring the evo......

Sequential Small Coronal Mass Ejections Observed In Situ and in White-Light Images by Parker Solar Probe

期刊: ASTROPHYSICAL JOURNAL, 2023; 953 (2)

We reconstruct the morphology and kinematics of a series of small transients that erupted from the Sun on 2021 April 24 using observations primarily f......

HOW-MHD: A High-order WENO-based Magnetohydrodynamic Code with a High-order Constrained Transport Algorithm for Astrophysical Applications

期刊: ASTROPHYSICAL JOURNAL, 2023; 953 (1)

Due to the prevalence of magnetic fields in astrophysical environments, magnetohydrodynamic (MHD) simulation has become a basic tool for studying astr......

The Correlations of Stellar Tidal Disruption Rates with Properties of Massive Black Holes and Their Host Galaxies

期刊: ASTROPHYSICAL JOURNAL, 2023; 952 (2)

Stars can be either disrupted as tidal disruption events (TDEs) or swallowed whole by massive black holes (MBHs) at galactic centers when they approac......

Gravitational Wave Eigenfrequencies from Neutrino-driven Core-collapse Supernovae

期刊: ASTROPHYSICAL JOURNAL, 2023; 954 (2)

Core-collapse supernovae (CCSNe) are predicted to produce gravitational waves (GWs) that may be detectable by Advanced LIGO/Virgo. These GW signals ca......
