—
in AstronomyThree ultra-faint Milky Way satellites identified in DELVE survey data, including the faintest known satellite in the outer halo and an ambiguous compact system.
Tomographic line analysis identifies possible embedded planets in disks
—
in AstrophysicsTomographic analysis of molecular line observations enables detection of embedded planets in protoplanetary disks, revealing multiple planet candidates in HD 135344B and MWC 758.
Large protoplanetary disks show widespread non-Keplerian gas motions
—
in AstrophysicsTwo-dimensional kinematic mapping of 15 protoplanetary disks reveals ubiquitous non-Keplerian deviations including spiral structures, with systematic differences between disk classifications.
Vertical gas flows are widespread in protoplanetary disks
—
in AstrophysicsStudy of vertical gas flows in 14 protoplanetary disks using ALMA observations reveals ubiquitous vertical motions driven by diverse physical mechanisms during planet formation.
TransFit-CSM models interaction-powered transients with consistent shock diffusion
Fast, physically consistent framework for modeling interaction-powered transients through self-consistent ejecta-CSM shock and radiative diffusion coupling.
Dark matter halo alters black hole optics and thermodynamics
Exact black hole solution in cored Plummer dark matter halo showing modified photon dynamics, shadows, lensing, quasinormal modes, and novel phase transitions absent in Schwarzschild spacetime.
