The Astrophysical JournalWe investigate how stellar disks sustain their ultrathin structure throughout their evolution. We follow the evolution of ultrathin stellar disks with varying dark matter (DM) halo concentration ( c ) using collisionless N -body simulations with AREPO ...

Analysis of DQZ White Dwarf Evolution through Procyon
The Astrophysical JournalProcyon is a great system to probe stellar evolution of noninteracting binaries. We present an extensive grid of Modules for Experiments in Stellar Astrophysics evolutionary tracks to constrain the evolution of Procyon A and B. We systematically vary the

Protoplanetary disc population synthesis
Astronomy & AstrophysicsContext. Protoplanetary discs are the birthplaces of planets, and their lifetimes determine the time available for planet formation. Recent studies have highlighted the importance of stellar mass sampling when determining disc lifetimes through the ...

Coevolution of Nuclear Star Clusters and Massive Black Holes: Extreme-mass-ratio Inspirals
The Astrophysical JournalWe explore extreme-mass-ratio inspirals (EMRIs) in the coevolution of massive black holes (MBHs) and nuclear star clusters (NSCs), which host diverse stellar populations across a wide range of masses. The dynamics are simulated self-consistently with GNC

The Astrophysical JournalPeas-in-a-Pod (PIAP) systems have been shown to be common across exoplanet systems, with regular planet spacings and similar planet sizes. In contrast, ultra-short-period planets have displayed distinct differences from PIAP systems, including higher ...

The evolution of high-z proto-star clusters into local globular clusters
Astronomy & AstrophysicsThe James Webb Space Telescope (JWST) detected numerous massive and relatively compact stellar clumps around proto-galaxies at high redshift (z > 0.5).

Barred Galaxies in MaNGA: Stellar Mass Dependence and Black Hole Growth
The Astrophysical JournalThis study investigates the role of internal structures, such as stellar bars and active galactic nuclei (AGN), in shaping galaxy evolution using 7408 galaxies (2641 barred) from the Sloan Digital Sky Survey IV Mapping Nearby Galaxies at Apache Point ...
