Spectral evolution of the narrow emission line components in optical during the 2022 nova eruption of U Scorpii Open

Katsuki Muraoka, Naoto Kojiguchi, Junpei Ito, Daisaku Nogami, Taichi Kato , et al. · 2025

There remains debate over whether the accretion disk survives or is entirely disrupted after the nova eruption. In our previous paper, Muraoka et al. (2024, PASJ, 76, 293) have photometrically demonstrated that the surviving accretion disk…

A planetary collision afterglow and transit of the resultant debris cloud Open

Matthew A. Kenworthy, Simon J. Lock, Grant M. Kennedy, Richelle van Capelleveen, Eric E. Mamajek , et al. · 2023

Planets grow in rotating disks of dust and gas around forming stars, some of which can subsequently collide in giant impacts after the gas component is removed from the disk. Monitoring programs with the warm Spitzer mission have recorded …

V618 Sgr: Galactic eclipsing symbiotic nova detected in repeated outbursts Open

Jaroslav Merc, R. Gális, P Velez, S. Charbonnel, O. Garde , et al. · 2023

V618 Sgr was previously classified as an R CrB-type variable and later as a possible symbiotic star. Our study aims to analyse the nature of this target, which is currently undergoing significant brightening in properties similar to those …

Gaia22eor: Symbiotic Star V2756 Sgr Detected in a Deep Eclipse Open

Jaroslav Merc, Hamish Barker, R. Gális · 2022

V2756 Sgr is a long-known S-type symbiotic binary that was recently detected in ∼1 mag eclipse-like fading by the Gaia satellite. This behavior was reported as a Gaia Science Alert under the designation Gaia22eor. V2756 Sgr has not been re…

ASASSN-21co: A Detached Eclipsing Binary with an 11.9 yr Period Open

D. M. Rowan, K. Z. Stanek, Z. Way, C. S. Kochanek, T. Jayasinghe , et al. · 2021

We use ASAS V -band and ASAS-SN g -band observations to model the long-period detached eclipsing binary ASASSN-21co. ASAS observations show an eclipse of depth V ∼ 0.6 mag in 2009 April. ASAS-SN g -band observations from 2021 March show an…
