The nearby Type II supernova 2024ggi beyond 600 days: circumstellar interaction and dust formation
L. Ferrari, G. Folatelli, C. P. Gutiérrez +16
The Type II SN 2024ggi is one of the nearest core-collapse SNe to have exploded in recent decades. Its proximity has enabled extensive multiwavelength monitoring from early times t…
The hydrogen-free circumstellar interaction in the Type Ib supernova 2021efd: A clue to the mechanism of the helium-layer stripping
N. Pyykkinen, T. Nagao, H. Kuncarayakti +27
Stripped-envelope supernovae (SESNe), including Type IIb, Ib, and Ic supernovae (SNe), originate from the explosions of massive stars whose outer envelopes have been largely remove…
JWST Observations of SN 2024ggi II: NIRSpec Spectroscopy and CO Modeling at 285 and 385 Days Past the Explosion
T. Mera, C. Ashall, P. Hoeflich +20
We present James Webb Space Telescope (JWST) NIRSpec observations of SN~2024ggi, spanning wavelengths of 1.7--5.5 micron at +285.51 and +385.27 days post-explosion. These nebular s…
The nebular phase of SN 2024ggi: a low-mass progenitor with no signs of interaction
L. Ferrari, G. Folatelli, K. Ertini +14
Context: SN 2024ggi is a Type II supernova (SN) discovered in the nearby galaxy NGC 3621 (D Mpc) on 2024 April 03.21 UT. Its proximity enabled a detailed investi…
SN 2023ixf: interaction signatures in the spectrum at 445 days
Gastón Folatelli, Lucía Ferrari, Keila Ertini +2
SN 2023ixf is one of the most neaby and brightest Type II supernovae (SNe) of the past decades. A rich set of pre-explosion data provided important insight on the properties of the…
Progenitor mass and ejecta asymmetry of SN 2023ixf from nebular spectroscopy
Lucía Ferrari, Gastón Folatelli, Keila Ertini +2
Context. SN 2023ixf was discovered in Galaxy M101 in May 2023. Its proximity made it an extremely valuable opportunity for the scientific community to study the characteristics of…
Late-time H/He-poor circumstellar interaction in the type-Ic supernova SN 2021ocs: an exposed oxygen-magnesium layer and extreme stripping of the progenitor
H. Kuncarayakti, K. Maeda, L. Dessart +14
Supernova (SN) 2021ocs was discovered in the galaxy NGC 7828 () within the interacting system Arp 144, and subsequently classified as a normal type-Ic SN around peak b…
