AT 2021hdr: A candidate tidal disruption of a gas cloud by a binary super massive black hole system
L. Hernández-García, A. M. Muñoz-Arancibia, P. Lira +25
With a growing number of facilities able to monitor the entire sky and produce light curves with a cadence of days, in recent years there has been an increased rate of detection of…
Tuning into spatial frequency space: Satellite and space debris detection in the ZTF alert stream
J. P. Carvajal, F. E. Bauer, I. Reyes-Jainaga +6
A significant challenge in the study of transient astrophysical phenomena is the identification of bogus events, among which human-made satellites and debris in Earth orbit remain…
A Novel Optimal Transport-Based Approach for Interpolating Spectral Time Series: Paving the Way for Photometric Classification of Supernovae
M. Ramirez, G. Pignata, Francisco Förster +7
This paper introduces a novel method for creating spectral time series, which can be used for generating synthetic light curves for photometric classification but also for applicat…
Impact of current uncertainties in the 12C+12C nuclear reaction rate on intermediate-mass stars and massive white dwarfs
Francisco C. De Gerónimo, Marcelo M. Miller Bertolami, Tiara Battich +6
Recent determinations of the total rate of the 12C+12C nuclear reaction show non-negligible differences with the reference reaction rate commonly used in previous stellar simulatio…
Unveiling the nature of two dwarf novae: CRTS J080846.2+313106 and V416 Dra
Arti Joshi, Márcio Catelan, Simone Scaringi +8
We present the analysis of optical photometric and spectroscopic observations of two non-magnetic cataclysmic variables, namely CRTS J080846.2+313106 and V416 Dra. CRTS J080846.2+3…
ATAT: Astronomical Transformer for time series And Tabular data
G. Cabrera-Vives, D. Moreno-Cartagena, N. Astorga +14
The advent of next-generation survey instruments, such as the Vera C. Rubin Observatory and its Legacy Survey of Space and Time (LSST), is opening a window for new research in time…
The most variable VVV sources: eruptive protostars, dipping giants in the Nuclear Disc and others
P. W. Lucas, L. C. Smith, Z. Guo +16
We have performed a comprehensive search of a VISTA Variables in the Via Lactea (VVV) database of 9.5 yr light curves for variable sources with mag, aiming to provide…
Spectroscopic confirmation of high-amplitude eruptive YSOs and dipping giants from the VVV survey
Zhen Guo, P. W. Lucas, R. Kurtev +17
During the pre-main-sequence (pre-MS) evolution stage of a star, significant amounts of stellar mass are accreted during episodic accretion events, such as multi-decade FUor-type o…
