Astronomers have seen some unimaginable occurrences throughout area and time.
There are novae: fusion flares on white dwarf stars’ surfaces.
There are supernovae: explosive stellar cataclysms.
In between these two are a novel phenomenon: luminous pink novae.
These outbursts persist for months, glowing and echoing in seen and infrared gentle.
V838 Monocerotis emitted a spectacular one in 2002.
The main clarification is a mergeburst: when two stars, already involved, merge into one.
The merging contact binaries V4332 Sagittarii and V1309 Scorpii created luminous pink novae.
Such identifications led to a query, “can we predict the subsequent luminous pink nova?”
Maybe: by observing contact binaries with quickening orbital intervals.
Because the interval shortens, the 2 stars method a merger.
When a crucial “closeness” is reached, it triggers a luminous pink nova.
The binary system KIC 9832227 appeared good: a contact binary whose interval is shortening.
A 2017 prediction, utilizing new and archival knowledge, indicated an upcoming merger in 2022.
Nevertheless, a timing error was swiftly uncovered and corrected, negating the 2022 prediction.
As an alternative, the interval first lengthened earlier than just lately shortening, presenting one more thriller.
KIC 9832227 might ultimately make a luminous pink nova, however in all probability not in 2022.
