How to calculate the goldilocks zones of brown dwarf stars? Do any encroach on the stars' Roche limit?

Ignoring tidal heating and such, how can one calculate the habitable orbital ranges for M, L, T, and Y spectral class stars? The reason I ask is that I'm also curious if any of these zones encroach on their respective Roche limits.

Given proper temperature and luminosity, Is the Circumstellar Habitable Zone larger for larger stars?

I was seeing a size comparison video of the size of the Sun with other stars, and I could see there are stars hundreds of times larger than the Sun. I understand the Circumstellar Habitable Zone depends on temperature and luminosity. Given proper…

What is the Habitable zone all about?

I've a question on Habitable zone. Does Habitable zone represent the region where we humans or the living beings of earth can survive? Or is it a region where life can exist? If it is second I want to know what are the parameters that are considered…

Do secondary stars in binary systems affect how the habitable zone is calculated or they can be calculated separately?

I was taking a look at this tool to calculate habitable zones: Calculation of habitable zones which is pretty simple: you need to input Teff in Kelvins and Stellar Luminosity in solar units. Then I was wondering if this calculation is affected when…

Better than Earth habitability

Earth undoubtly has very good conditions for supporting life. Although it is expected that many other planets on the outer space have conditions at least as good as Earth, the vast majority doesn't, making them unhospitable to life or probably being…

Luminosity in polar regions

I tried to find the habitable planets, thus I suppose to calculate the effective temperatures that incident on the planets from their host stars, I used $$ T_\mathrm{eff}=\frac{L}{4\pi\sigma_\mathrm{SB}R^2} $$ but I don't know how to calculate the…

Habitable Planet around Red Dwarf

Is there the possibility for a habitable Planet around a red dwarf? It is not required that the whole surface is habitable, but it shouldn't be a tiny spot. After reading a bit I assume the planet would be tidally locked to the star, with the side…

Why bother looking for Earth-like planets?

Is it really necessary to look for Earth-like habitable zone planets, when it is likely that the "humans" to reach that planet will be bio-engineered or entirely mechanical by the time we would be exploring "in person?"
