JWST nebular spectra detect cooling ~400 K carbonaceous dust emission in normal SN Ia 2023qov at +276 and +363 days, modeled as pre-existing circumstellar dust with mass ~10^{-4} M_sun located within ~1 light year.

Hierarchical Bayesian power-law fits to early ZTF light curves of 972 SNe Ia yield population parameters for rise time, index, and color evolution, revealing a bifurcation with SALT2 stretch.
Synthetic observables from tECSN models show slower early red-color decline due to higher Ti/Cr and a late-time 12.8 μm Ne II line that strengthens over time, unlike comparable CO deflagration models.
A new redshift-correlation technique with third-generation GW detectors can constrain the BNS contribution to cosmic r-process nucleosynthesis to 5-6% precision via Fisher forecasts on mock bright- and dark-siren data.
Detection of helium lines in Balmer-dominated shocks of Type Ia SNRs reveals enhanced helium in some remnants and challenges shock models, enabling new constraints on progenitor environments.
3D simulations find that the convective Urca process reduces mixing efficiency near the convective boundary in a simmering white dwarf but does not restrict the overall size of the convection zone, with the A=23 pair having the largest effect.
3D simulations show the convective Urca process substantially reduces the convection zone size in a simmering white dwarf, though convection extends past the Urca shell.
3D nebular spectra calculations for double-detonation Type Ia supernova models reveal viewing-angle dependent line profiles and tentatively support primary-only detonation over secondary detonation based on comparisons to observations.
BayeSN analysis of ZTF Type Ia supernovae confirms a ~0.1 mag intrinsic environmental step in standardized brightness that is not explained by differences in dust extinction properties.
Multi-survey analysis of 157 hot subdwarf binaries yields 23 orbital solutions (11 new) whose mass-period distribution matches post-common-envelope systems, supporting a common-envelope origin.
Mock catalogs of Milky Way white dwarf mergers are created with COSMIC and released publicly, summarizing outcomes by mass and composition while varying binary evolution uncertainties to connect with LISA sources.
Reconstruction of GRO J1655-40, SAX J1819.3-2525 and 4U 1543-47 requires CE efficiencies α_0.5U ≳6.7, α_U ≳4.2, α_H ≳1.7 with no solutions below unity, implying need for additional energy or formalism changes plus natal kicks ≳50 km/s for 4U 1543-47.
