ALMA Spots Multi-Ring Structure around Rapidly-Evolving Carbon Star

Mar 29, 2022 by News Staff

Using the Atacama Large Millimeter/submillimeter Wave Array (ALMA), astronomers have observed the carbon-rich star V Hydrae that is apparently transitioning...

This Hubble image shows the carbon star CW Leonis. The image incorporates observations from 2011 and 2016 by Hubble’s Wide Field Camera 3 (WFC3). The star is brightest in the red filters, R and I, and therefore the simmering orange color pervading the center of the image well represents the real color of the star.

CW Leonis, which is located 400 light-years away in the constellation of Leo, is a carbon star — a luminous type of red giant star with a carbon-rich...

Palmerini et al. analyzed the isotopic composition of heavy neutron capture elements measured in SiC stardust grains extracted from pristine meteorites, interpreting them as the outcome of s-process nucleosynthesis occurring in the AGB stages of stars with masses between two and three solar masses and solar metallicities.
