As Wats points out, the effect of the resistance differs (due to different surface/mass ratio) and lower speed is bad for a planet in orbit but good for a creature.

It's really interesting I didn't think a planet could survive for that long, but at the top end being able to exist in the atmosphere of its parent star for a few million years is quite interesting. I dont think this is modeled in SE; I haven't seen any planet inside the atmosphere of its parent star (although I've seen a few that look like comets because their atmospheres are being burned away).As Wats points out, the effect of the resistance differs (due to different surface/mass ratio) and lower speed is bad for a planet in orbit but good for a creature.

A planet inside its star would not be observed directly. Rather, we would observe the effects (described earlier) on the star. This could be detected by amateur astronomers, if they are lucky enough to find one. The hardest part isn't the detection itself but ruling out other plausible causes for the star's behavior.
I thought perhaps we could use the transit method the way Kepler used it...I remember one of our posters actually outlined how to do it with a mirrorless or dslr camera and a moderate focal length lens. (I think he mentioned that a 50mm lens was recommended- though I'm not sure if he meant the objective diameter of the lens or the focal length.) To rule out other plausible causes, I take it we would need some sort of professional confirmation (could that be provided by spectroscopic analysis of the star or what you mentioned earlier, by measuring its angular momentum and finding the star to be spinning unusually rapidly?)A planet inside its star would not be observed directly.

Nothing too special, just the 11-year solar cycle doing its thing. I look forward to seeing how the corona looks in the 2024 eclipse.
omg yes! and sorry about that! Are you coming here for the April 2024 eclipse? I'm making plans to see it in upstate NY....I just hope the weather cooperates. Do you remember in the last American eclipse there were pictures of the total eclipse with pink protuberances clearly visible? I hope we get to see the same this time! Is there any particular equipment you recommend? I'm bringing my eclipse glasses and my mirrorless camera and a 75-300 lens. I was wondering if I should get a special solar filter for the camera lens (58mm filter thread) or use a spare pair of eclipse glasses as a makeshift filter?Nothing too special, just the 11-year solar cycle doing its thing.

Also, please make an effort to cut down on the amount of multi-posting. There has been a lot of it lately, and it's getting tiring to edit them together.
Currently planning for Texas where the chances of clear skies are greatest (besides in Mexico, but fewer roads and services along the track there). And yes, hard to forget the prominences which were spectacular in the 2017 eclipse. The largest was visible (barely) with the naked eye. Good chance of seeing them again in 2024 -- they're usually seen in every total eclipse, but typically need a little magnification to spot. The pink arc of chromosphere is also stunning, and much easier to see with the unaided eye.
Your eyes. Anything else is a bonus but which also must be factored for the limited time you have. Totality goes by very fast and it's easy to try to do too much.
Yes, thanks for reminding me Wat Is 75-300 with a 2x crop sensor going to be enough to frame the corona tightly?Currently planning for Texas where the chances of clear skies are greatest (besides in Mexico, but fewer roads and services along the track there).

Binoculars are nice for a closeup of the Sun during totality, and bring any camera equipment you're comfortable with. In 2017 I used my DSLR with a telephoto lens for the Sun, and GoPro to capture the changing lighting conditions and crowd reaction during and just before/after totality. If you want to get good photos of the corona with your telephoto, be sure to take a lot of shots at very different exposures. The corona spans a very wide range of brightnesses. The corona is also much bigger than you might expect, and too much zoom might mean missing the outer parts of it.
Personally, I don't bother with solar filters. Not because they're not needed outside of totality (they absolutely are), but because I'm less interested in photographing the partial phases, opting instead to observe the surroundings with my eyes and occasionally glancing at the Sun with eclipse glasses.
I recommend you not use your binoculars on the Sun outside of totality. Unless you have a proper solar filter to put in front of your equipment (not behind it!), then it's a bad idea for both your equipment and your eyes. Magnification and light gathering power and the Sun do not mix.
Unlikely. It's overcast here. 97% partial lunar eclipse should be deep enough to see some of the red/copper color of the umbra, but the remaining sliver will still be fairly bright and might drown the umbral shadow out a bit. It will be easier to see with magnification, or with a camera. Yes, give your camera and zoom lens a try on the Moon. It will give good sense for shooting the Sun during the solar eclipse as well, since it's nearly the same size. And for the corona, imagine it spreading about 2 Sun or Moon diameters away:
