A Flare for Barnard's Star

Barnard's Star, the second nearest star system to the Sun, spewed a large
flare that increased its brightness, say astronomers. The discovery is a
surprise: the star should be sedate, because it's an old red dwarf.

So then if logic dictates than the sun has a chance of ejecting a flare,
too! Right!


And does so frequently. What do you think causes aurora.

Your logic doesn't follow because the Sun is not an old red dwarf.

Typo, that should read:

"Your logic doesn't follow JUST because the Sun is not an old red
dwarf."

To clarify, other types of star might also be 'sedate'. As it happens,
the Sun is not, but your logic remains wrong.

But those don't markedly increase the total brightness of the sun
(fortunately for us).
AIUI, "superflares" that could do so were proposed as a cause of melting
of some rocks brought back by Apollo 11, but that hasn't been confirmed
and there's no other evidence that they occur here.

Barnard's Star was only noticed because it has the highest proper motion
across the sky than any other extra-solar object. It is bookin', dude,
and so it is unusual, and now it has exhibited an unusual flare, so it
is now a perplexity that cries out to be investigated.
