   …a transiting sub-Neptune candidate with a period of 36.34 days around TIC 402710280 (TYC 9041-03677-1), a K dwarf of TESS magnitude 9.24 at 66.8 pc that the Transiting Exoplanet Survey Satellite (TESS) has observed…

3. The DARWIN Project: Cosmological Simulations of Galaxy Formation down to Dwarf Scales in Diverse Environments astro-ph.GA · 19 Oct · 4 hits

   We present the DARWIN project, a suite of cosmological simulations with RAMSES to study dwarf-galaxy formation and evolution across diverse environments. DARWIN-1 is a full-box simulation in a…

   …by constraining stripped H/He-rich material and iron-group abundances sensitive to the progenitor white dwarf density. We report the non-detection of narrow H/He features in nebular phase optical/NIR spectra of SN…

5. Forecasting the Resolvability of Stellar Velocity Dispersions in Ultra-faint Dwarf Galaxies astro-ph.GA · 17 Oct · 3 hits

   Ultra-faint dwarf galaxies (UFDs)---the smallest and most dark-matter dominated galactic systems---push the boundaries of…

6. Magnetic-field constraints for four magnetic cataclysmic variables from simultaneous continuum and cyclotron modeling astro-ph.SR · 16 Oct · 1 hit

   …a simultaneous continuum-cyclotron analysis to four DESI/LAMOST magnetic-CV candidates. We fit a white dwarf atmospheric model, a hot-spot blackbody, and an isothermal constant-$\Lambda$ cyclotron component in…
