Between Plateaus and Slopes: A Data-Driven Exploration of Spectral Diversity Across Type IIP/L Supernovae
Géza Csörnyei, Claudia P. Gutiérrez
Type II supernovae (SNe II) have been traditionally separated into several subgroups based on their photometric and spectroscopic properties, but whether these represent distinct p…

Progenitor Insights of Type IIP SN 2018pq: A Comprehensive Photometric and Spectroscopic Study
Monalisa Dubey, Kuntal Misra, Raya Dastidar +10
We present high-cadence photometric and low-resolution (R 400--700) optical spectroscopic observations of Type IIP supernova, SN~2018pq, which exploded on the outskirts of t…

Asteroid sizes determined with thermophysical model and stellar occultations
A. Choukroun, A. Marciniak, J. Äurech +165
Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…
