Pulsating B stars in the Scorpius-Centaurus Association with TESS
Awshesh N. Sharma, Timothy R. Bedding, Hideyuki Saio +1
We study 119 B stars located in the Scorpius-Centaurus Association using data from NASA's TESS Mission. We see pulsations in 81 stars (68%) across the full range of effective tempe…

Fully self-consistent nova explosion models reproducing light curves of KT Eri, V339 Del, V597 Pup, and SMC NOVA 2016-10a
Mariko Kato, Izumi Hachisu, Hideyuki Saio
The rising phase toward the optical maximum of a classical nova is one of the last frontiers of nova study. Constructing free-free emission model light curves based on our fully se…

A comprehensive light curve model of the very fast nova V1674 Herculis
Mariko Kato, Izumi Hachisu, Hideyuki Saio
V1674 Her is one of the fastest novae, of which the very early phase is well observed including optical rise to the peak over 10 magnitudes. We present a full theoretical light cur…
