“…Maeda et al (2021) argue that the variation in the mass-loss rate only by a factor can emerge as an observational peculiarity in radio light curves of SNe. Maeda et al (2023) also suggest that the elevation of the mass-loss rate by an order of magnitude could be an explanation for the radio rebrightening of SNe. Other cases are that Weil et al (2020) and Kilpatrick et al (2022) ascribe the origin of the excess in the optical light curves as the existence of the CSM with their mass-loss rates not so much higher (M M 10 10 yr…”

“…The variety of hydrodynamical structures of the CSM would give rise to observational characteristics of subsequent SNe, such as the excess in the optical emission and the rebrightening of radio emission in the late phase of SN−CSM interaction (e.g., Weil et al 2020;Kilpatrick et al 2022;Maeda et al 2023). Here we discuss the possibility that our results can give explanations for characteristics of SNe indicated by late-phase observations.…”

“…Another example is that a few SNe are considered to undergo CSM interaction in the late phase (∼several years after the explosion; see, e.g., Weil et al 2020;Kilpatrick et al 2021Kilpatrick et al , 2022). As an extreme example of the late-phase CSM interaction, it is argued that there are several objects exhibiting the transformation of the SN type from a stripped-envelope SN to a Type IIn SN (Margutti et al 2017;Tinyanont et al 2019;Chandra et al 2020;Tartaglia et al 2021), or showing the rebrightening of radio emission (Mauerhan et al 2018;Balasubramanian et al 2021;Maeda et al 2023). These objects are speculated to have shell-structured CSM detached from the progenitor, highlighting the possible mass ejection of the progenitor in the past (see the discussion in Maeda et al 2023).…”

Binary Interaction Can Yield a Diversity of Circumstellar Media around Type II Supernova Progenitors

Recent observations of supernovae (SNe) have indicated that a fraction of massive stars possess dense circumstellar medium (CSM) at the moment of their core collapses. They suggest the presence of additional activities of the SN progenitor driving the enhancement of the mass-loss rate, and some physical processes attributing to a single star’s activities have been considered. In this study, we carry out binary evolutionary simulations of massive stars by MESA and investigate effects on the subsequent CSM formation through hydrodynamical simulations by PLUTO. We show that the mass transfer rate in a binary can increase at the beginning of the Roche lobe overflow, and this enhancement would be associated with the structure of the CSM before the explosion. We also illustrate that, depending on the orbital period of the binary, the density structure of the CSM can have a diverse distribution, including shell-like and cliff-like structures. These characteristic structures appear within the length scale of ∼1017 cm and could be traced by long-term observations of SNe, if the slow velocity of the CSM is assumed (∼10 km s−1). Our results highlight the importance of binary interaction in the aspect of reproducing the diversity of the CSM configuration.

“…Maeda et al (2023b) considered SN 2018ivc as a possible variant of a SN II-L, with transitional characteristics between SNe II-P and IIb. Interaction of the SN shock with preexisting wind matter appears to be playing a strong role in the SN's emission (Maeda et al 2023b), with origins in a progenitor experiencing an extreme form of binary evolution (Maeda et al 2023a). The SN was detected in our HST F555W and F814W Snapshots obtained on 2020 November 27, 739 days (2.0 yr) after discovery.…”

A Snapshot Survey of Nearby Supernovae with the Hubble Space Telescope

Over recent decades, robotic (or highly automated) searches for supernovae (SNe) have discovered several thousand events, many of them in quite nearby galaxies (distances < 30 Mpc). Most of these SNe, including some of the best-studied events to date, were found before maximum brightness and have associated with them extensive follow-up photometry and spectroscopy. Some of these discoveries are so-called “SN impostors,” thought to be superoutbursts of luminous blue variable stars, although possibly a new, weak class of massive-star explosions. We conducted a Snapshot program with the Hubble Space Telescope (HST) and obtained images of the sites of 31 SNe and four impostors, to acquire late-time photometry through two filters. The primary aim of this project was to reveal the origin of any lingering energy for each event, whether it is the result of radioactive decay or, in some cases, ongoing late-time interaction of the SN shock with preexisting circumstellar matter, or the presence of a light echo. Alternatively, lingering faint light at the SN position may arise from an underlying stellar population (e.g., a host star cluster, companion star, or a chance alignment). The results from this study complement and extend those from Snapshot programs by various investigators in previous HST cycles.

“…The binary interaction is believed to play a key role for these SNe IIb (e.g., Benvenuto et al 2013;OM17) and thus the massloss rate is highly affected by the binary interaction (e.g., Smith 2014, for a review). Depending on the binary separation and mass ratio, the binary evolution could lead to a diversity in the mass-transfer history (e.g., Maeda et al 2023b).…”

We present optical, near-infrared, and radio observations of supernova (SN) SN IIb 2022crv. We show that it retained a very thin H envelope and transitioned from an SN IIb to an SN Ib; prominent Hα seen in the pre-maximum phase diminishes toward the post-maximum phase, while He i lines show increasing strength. SYNAPPS modeling of the early spectra of SN 2022crv suggests that the absorption feature at 6200 Å is explained by a substantial contribution of Hα together with Si ii, as is also supported by the velocity evolution of Hα. The light-curve evolution is consistent with the canonical stripped-envelope SN subclass but among the slowest. The light curve lacks the initial cooling phase and shows a bright main peak (peak M V = −17.82 ± 0.17 mag), mostly driven by radioactive decay of 56Ni. The light-curve analysis suggests a thin outer H envelope (M env ∼ 0.05 M ⊙) and a compact progenitor (R env ∼ 3 R ⊙). An interaction-powered synchrotron self-absorption model can reproduce the radio light curves with a mean shock velocity of 0.1c. The mass-loss rate is estimated to be in the range of (1.9−2.8) × 10−5 M ⊙ yr−1 for an assumed wind velocity of 1000 km s−1, which is on the high end in comparison with other compact SNe IIb/Ib. SN 2022crv fills a previously unoccupied parameter space of a very compact progenitor, representing a beautiful continuity between the compact and extended progenitor scenario of SNe IIb/Ib.
