Abstract:
We investigate the photometric characteristics of a sample of
intermediate-luminosity red transients (ILRTs), a class of elusive
objects with peak luminosity between that of classical novae and
standard supernovae. Our goal is to provide a stepping stone in the
path to reveal the physical origin of such events, thanks to the
analysis of the datasets collected. We present the multi-wavelength
photometric follow-up of four ILRTs, namely NGC 300 2008OT-1, AT
2019abn, AT 2019ahd, and AT 2019udc. Through the analysis and
modelling of their spectral energy distribution and bolometric light
curves, we inferred the physical parameters associated with these
transients. All four objects display a single-peaked light curve which
ends in a linear decline in magnitudes at late phases. A flux excess
with respect to a single blackbody emission is detected in the
infrared domain for three objects in our sample, a few months after
maximum. This feature, commonly found in ILRTs, is interpreted as a
sign of dust formation. Mid-infrared monitoring of NGC 300 2008OT-1
761 days after maximum allowed us to infer the presence of about
0.00001 to 0.001 solar masses of dust, depending on the chemical
composition and the grain size adopted. The late-time decline of the
bolometric light curves of the considered ILRTs is shallower than
expected for 56Ni decay, hence requiring an additional powering
mechanism. James Webb Space Telescope observations of AT 2019abn prove
that the object has faded below its progenitor luminosity in the
mid-infrared domain, five years after its peak. Together with the
disappearance of NGC 300 2008OT-1 in Spitzer images seven years after
its discovery, this supports the terminal explosion scenario for
ILRTs. With a simple semi-analytical model we tried to reproduce the
observed bolometric light curves in the context of a few solar masses
ejected at few 1000 kilometer per second and enshrouded in an
optically thick circumstellar medium.
