The changing optical and X-ray emission of the dormant Cas star HD 45314
G. Rauw, Y. Nazé, E. Bryssinck +25
Cas stars are Oe/Be stars that exhibit bright and hard X-ray emission. HD45314 belonged to this category, but lost its Cas characteristics as its circumstellar disc started…
Symbiotic binaries in the Gaia data. II. Symbiotic candidates from general variability classification in DR3
Jaroslav Merc, Lionel Mulato, Joanna Mikołajewska +7
We investigate the reliability of the symbiotic star class in the general variability classification of Gaia DR3 and search for new genuine symbiotic systems among the objects assi…
Analysis of the Gaia DR3 planetary nebula candidates and the possible symbiotic stars among them
Lionel Mulato, Jaroslav Merc, Stéphane Charbonnel +3
The Gaia DR3, released in June 2022, included low-resolution BP/RP (XP) spectra that have been exploited for the classification of various types of emission-line objects using mach…
What determines the -ray luminosities of classical novae?
Peter Craig, Elias Aydi, Laura Chomiuk +25
Classical novae in the Milky Way have now been well-established as high-energy GeV -ray sources. In novae with main-sequence companions, this emission is believed to result from…
V4141 Sgr: Outflows and repeated outbursts
Jaroslav Merc, Joanna Mikołajewska, Thomas Petit +6
In this work, we analyze the ongoing brightening of the poorly studied symbiotic star V4141 Sgr and examine its long-term variability. We present new low-resolution spectroscopic o…
Spectral evolution of the narrow emission line components in optical during the 2022 nova eruption of U Scorpii
Katsuki Muraoka, Naoto Kojiguchi, Junpei Ito +20
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 pho…
Search for new Galactic Wolf-Rayet stars using Gaia DR3. I. Candidate selection and the follow-up of the bright sample
Lionel Mulato, Jaroslav Merc, Stéphane Charbonnel +3
Gaia DR3, released in June 2022, included low-resolution XP spectra that have been used for the classification of various types of emission-line objects through machine-learning te…
Revisiting the Classics: On the Optical Colours of Novae as Standard Crayons
Peter Craig, Elias Aydi, Laura Chomiuk +9
We present a systematic study of the colours of novae over the course of their eruptions. Where possible, interstellar reddening was measured using the equivalent widths of…
Gaia23ckh: Symbiotic outburst of the assumed Mira variable V390 Sco
Jaroslav Merc, Peter Velez, Stéphane Charbonnel +5
The poorly studied variable star V390 Sco, previously classified as a Mira pulsator, was detected in a brightening event by the ESA Gaia satellite in September 2023. This work pres…
A planetary collision afterglow and transit of the resultant debris cloud
Matthew Kenworthy, Simon Lock, Grant Kennedy +19
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. Monit…
