The double explosion of SN 2009ip in 2012 raises questions about our understanding of the late stages of massive star evolution. Here we present a comprehensive study of SN 2009ip during its remarkable rebrightenings. High-cadence photometric and spectroscopic observations from the GeV to the radio band obtained from a variety of ground-based and space facilities (including the Very Large Array, Swift, Fermi, Hubble Space Telescope, and XMM) constrain SN 2009ip to be a low energy (E similar to… 
The Type IIn Supernova SN 2010bt: The Explosion of a Star in Outburst
It is well known that massive stars (M > 8 M☉) evolve up to the collapse of the stellar core, resulting in most cases in a supernova (SN) explosion. Their heterogeneity is related mainly to different
Clues to the nature of SN 2009ip - II. The continuing photometric and spectroscopic evolution to 1000 days
The 2012 brightening of SN 2009ip was dominated by emission from the interaction of ejecta with the surrounding circumstellar material (CSM) produced by episodic mass loss from the progenitor,
SN Hunt 248: a super-Eddington outburst from a massive cool hypergiant
We present observations of SN Hunt 248, a new supernova (SN) impostor in NGC 5806, which began a multistage outburst in 2014 May. The ‘2014a’ discovery brightening exhibited an absolute magnitude of
Catching a star before explosion: the luminous blue variable progenitor of SN 2015bh
In this paper we analyse the pre-explosion spectrum of SN2015bh by performing radiative transfer simulations using the CMFGEN code. This object has attracted significant attention due to its
Ejection of the Massive Hydrogen-rich Envelope Timed with the Collapse of the Stripped SN 2014C.
TLDR
This analysis identifies SN 2014C-like signatures in ~10% of SNe, reasonably consistent with the expectation from the theory of recent envelope ejection due to binary evolution if the ejected material can survive in the close environment for 103-104 years.
SNhunt151: an explosive event inside a dense cocoon
SNhunt151 was initially classified as a supernova (SN) impostor (nonterminal outburst of a massive star). It exhibited a slow increase in luminosity, lasting about 450 d, followed by a major
Powering the second 2012 outburst of SN 2009ip by repeating binary interaction
We propose that the major 2012 outburst of the supernova impostor SN 2009ip was powered by an extended and repeated interaction between the Luminous Blue Variable (LBV) and a more compact companion.
The peculiar balmer decrement of SN 2009ip: Constraints on circumstellar geometry
We present optical and near-IR spectroscopic observations of the luminous blue variable SN 2009ip during its remarkable photometric evolution of 2012. The spectra sample three key points in the SN
A luminous stellar outburst during a long-lasting eruptive phase first, and then SN IIn 2018cnf
We present the results of the monitoring campaign of the Type IIn supernova (SN) 2018cnf (a.k.a. ASASSN-18mr). It was discovered about ten days before the maximum light (on MJD = 58 293.4 ± 5.7 in
PTF13efv—An Outburst 500 Days Prior to the SNHunt 275 Explosion and Its Radiative Efficiency
The progenitors of some supernovae (SNe) exhibit outbursts with super-Eddington luminosities prior to their final explosions. This behavior is common among SNe IIn, but the driving mechanisms of

EXPLAINING THE SUPERNOVA IMPOSTOR SN 2009ip AS MERGERBURST
We propose that the energetic major outburst of the supernova (SN) impostor SN 2009ip in 2012 September (outburst 2012b) was a mergerburst event, where two massive stars merged. The previous
SPECTRAL EVOLUTION OF THE EXTRAORDINARY TYPE IIn SUPERNOVA 2006gy
We present a detailed analysis of the extremely luminous and long-lasting Type IIn supernova (SN) 2006gy using spectra obtained between days 36 and 237 after explosion. We derive the temporal
The Rise of the Remarkable Type IIn Supernova SN 2009ip
Recent observations by Mauerhan et al. have shown the unprecedented transition of the previously identified luminous blue variable (LBV) and supernova (SN) impostor SN 2009ip to a real Type IIn SN
SUPERNOVA PTF 09UJ: A POSSIBLE SHOCK BREAKOUT FROM A DENSE CIRCUMSTELLAR WIND
Type-IIn supernovae (SNe IIn), which are characterized by strong interaction of their ejecta with the surrounding circumstellar matter (CSM), provide a unique opportunity to study the mass-loss
Superluminous Light Curves from Supernovae Exploding in a Dense Wind
Observations from the last decade have indicated the existence of a general class of superluminous supernovae (SLSNe), in which the peak luminosity exceeds 1044 erg s–1. Here we focus on a subclass
Supernova 1996L: evidence of a strong wind episode before the explosion
Observations of the Type II supernova (SN) 1996L reveal the presence of a slowly expanding (v∼ 700 km s-1) shell at ∼ 1016 cm from the exploding star. Narrow emission features are visible in the
The Unprecedented Third Outburst of SN 2009ip: A Luminous Blue Variable Becomes a Supernova
Some reports of supernova (SN) discoveries turn out not to be true core-collapse explosions. One such case was SN 2009ip, which was recognized to be a luminous blue variable (LBV) eruption. This
SN 2005cs in M51 – I. The first month of evolution of a subluminous SN II plateau
Early-time optical observations of supernova (SN) 2005cs in the Whirlpool Galaxy (M51) are reported. Photometric data suggest that SN 2005cs is a moderately underluminous Type II plateau SN (SN IIP).
