Q: Red giant heating effects on earth-like planets over time

Can anyone answer the following query or point me in a direction where I
might find relevant information?: What are the supposed red giant
heating effects on earth-like planets over time? I'm specifically
interested in transition points, times, where a planet might be liveable
for humans and then not be.

This has been one of James Nicoll's favorite topics.

That should give you a bunch of threads where your specific interests
are discussed.

I find that subject interesting but I bet you get a lot more
hits on my name and the words injury, pain, death or coffee, and a
million zillion hits on my name and that quotation of mine.

or coffee,

That I can relate to.

Do you get any royalties from the folks that use it?

Try googling 'increasingly exoskeletal man'. I like the phrase, so
I plan to use it often.

Ha ha ha ha ha ha. No.

I did get a mention in a Chinese gov't ESL text, so I may well be
known to several hundred million Chinese, fwiw. It's a shame my last name
isn't as appropriate in Chinese as in Japanese, though.

_Yet_. I can name any number of relatives who came back from
the dead, as long as that number is three, but eventually something
did them in permanantly. Although in retrospect, maybe cremation did
the trick. Ah, well, water under the bridge.

No, it has to do with the peculiar attraction my family
has for cats. You could drop one of us on a deserted island, thousands
of miles from the nearest land, and a half-starved stray cat would turn
up, looking for scraps. Half the time, it would have a litter of kittens
trailing along. This goes back to the 19th century, at least. In my
case, I've got saddled with a collection of animals that are also mostly
problem cases, animals that I couldn't find homes for because of health
issues or profound mental problems, from retardation to severe periodic
paranoia, the sort that makes a cat attack its own food dish.

Japanese for cat is Neko or Nekko. Nicoll, if the speaker
is a Japanese employee on our Maui farm, sounds close enough that
my great-grandfather's employees thought the cat-thing was hilarious.

Well as I understand it when the Sun becomes a Red Giant, it will swell in
size to be as big as Mars' orbit. So, terrestial planets will be engulfed.
But don't worry that won't happen for another several billion years.

I'm aware of this future state for the Sun and the Earth, but what I'm
trying to figure out is whether there could be a time when a planet was
habitable and then a transition period to inhabitable that was short
enough to make an interesting story. It doesn't have to be the Sun and
the Earth. It could be any hypothetical star and planet possible. See,
if it takes a few million years to go from really bright to unliveable,
there would be a lot of incentive to learn how to fly away in space
craft.

I seem to recall (but can't find an URL) that once the hypothetical
oceans of Venus exceeded the magic number of mumble degrees, the boil-off
occured fairly rapidly, although since I can't find actual -numbers- I
can't say if that's rapid as humans measure things or as mountains do.

The red giant phase of a star is, unfortunately, not brief as
humans measure time. It's not even brief as mountains measure things.
