- Calcium-rich supernova - Wikipedia
In astronomy, a calcium-rich supernova (or Calcium-rich transient, Ca-rich SN) is a subclass of supernovae that, in contrast to more well-known traditional supernova classes, are fainter and produce unusually large amounts of calcium
- [2005. 02992] Calcium-rich Transient SN 2019ehk in A Star-Forming . . .
It, however, shows a few distinguishable properties from the canonical Ca-rich transients: a short-duration first peak in the light curve, high peak luminosity, and association with a star-forming environment
- Calcium-rich Transient SN 2019ehk in a Star-forming Environment: Yet . . .
If SN 2019ehk and iPTF16hgs belong to the same subpopulation within the Ca-rich transient class (along with iPTF14gqr, as argued in this paper), it might suggest that this subpopulation has much more diverse properties than the other (main) population within the Ca-rich transient class
- The progenitors of calcium-rich transients are not formed
We present deep Very Large Telescope and Hubble Space Telescope observations of the nearest examples of Ca-rich ‘gap’ transients – rapidly evolving transient events, with a luminosity intermediate between novae and supernovae
- 16075 - Late-time Observations of Calcium-Rich Transient SN 2019ehk
The close proximity of SN 2019ehk provides the first opportunity to track the photometric evolution of a Ca-rich transient at late phases (>300 days) when the SN luminosity is governed by radioactive decay and or additional power sources e g , CSM, and is too faint for ground-based observatories
- Two New Calcium-rich Gap Transients in Group and Cluster Environments
We show that both transients have properties consistent with the class of calcium-rich gap transients, specifically lower peak luminosities and rapid evolution compared to ordinary supernovae, and a nebular spectrum dominated by [Ca II] emission
- Calcium-rich Transient SN 2019ehk in a Star-forming . . . - NASA ADS
However, it shows a few properties distinct from those of the canonical Ca-rich transients: a short-duration first peak in the light curve, high peak luminosity, and association with a star-forming environment
- Late-time Observations of Calcium-rich Transient SN 2019ehk Reveal a . . .
These observations represent the latest B -band to near-IR photometric measurements of a calcium-rich transient to date and allow for the first opportunity to analyze the late-time bolometric evolution of an object in this observational SN class
- SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient
SN 2022oqm is the 39th transient to be classified as a CaRT We present an aggregate list of all known CaRTs at the time of writing in Table 5, along with the original references and basic observational properties
- The progenitors of calcium-rich transients are not formed in situ
Abstract: We present deep Very Large Telescope and Hubble Space Telescope observations of the nearest examples of Ca-rich ‘gap’ transients – rapidly evolving transient events, with a luminosity intermediate between novae and supernovae
