Symbiotic binaries in the Gaia data. II. Symbiotic candidates from general variability classification in DR3
Jaroslav Merc, Lionel Mulato, Joanna MikoÅajewska +7
The paper evaluates how well Gaia DR3’s general variability classification identifies symbiotic binaries, finds that many new candidates are actually pulsating red giants, and uses…
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 fro…
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…
V4141 Sgr: Outflows and repeated outbursts
Jaroslav Merc, Joanna MikoÅajewska, 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…
