Companion Star, Not Supernova, May Explain Distant Star's Outbursts
A distant star that astronomers thought would soon explode as a supernova may instead be flaring because of a previously unseen companion, new research suggests.
For about a decade, astronomers have watched a distant star that seemed to be heading for a supernova, its outbursts taken as signs that a catastrophic explosion was coming.
New research points elsewhere. Rather than an impending explosion, a previously unseen companion may be responsible for the star's behavior, according to the report.
The work reframes a decade of assumptions about the star, though the companion explanation is a proposal rather than a confirmed result.
Our reading
Our view: this is a useful correction to a decade-long assumption, but the companion explanation is a proposal, not a settled result.
What to do or watch
Watch for follow-up observations that could confirm or rule out the proposed unseen companion, since the companion explanation is currently a proposal rather than a settled result. The unresolved question is whether the star is actually headed for a supernova or whether the companion alone accounts for the outbursts seen over the past decade.
