They do not, and the results are a little comical :LOL: A 1 GYr old L0 at 0.08 solar masses ends up with a temp of ... 42.55 K A 1 GYr old Y6 at ~0.013 solar mases ends up with a temp of about 27 K, which is a bit of a drop from the 300K of a Y5 Correction, I was using solar masses and the...

I think, in the interim, I'll peg a theoretical Y10 (X0?) at a diameter of 0.09 and interpolate between 0.01 and 0.09 from Y5 to Y9. Keep the diameter constant at 0.10, and drop the temp by 50K per step. I've seen values floated of 80 K, 200 K, and 250 K as the theoretical minimum temp of a Y9...

Yes, it's me again :LOL: I'm working with some Brown Dwarfs, and I'm trying to wrap my head around aging. Well, with characteristics in general past Y5. How do you determine values for Y6 to Y9? The chart on page 226 doesn't extend past Y5, which is fine if you're not aging the Brown Dwarf -...

Heh, no worries - less concerned about a PhD thesis and more concerned about consistency and reproducibility, and this helps greatly. Now that I know that you were using diameters to compute size, rather than just use size, the pieces fall in to place, lol. So to sum up, the disconnect seems...

Okay, updating my spreadsheet I have the following: M = 1 S = 2 e = 0.0549 a = 0.384399 P = 27.321661 m = 0.0123 THF = (M^2 * S^5 * e^2) / (3000 * a^6 * P * m) = (1^2 * 2^5 * 0.0549^2) / (3000 * 0.384399^6 * 27.321661 * 0.0123) = (1 * 32 * 0.00301401) / (3000 * 0.00301401 * 27.321661 *...

Hi. It's me, I'm the problem, it's me. As long as we're bringing this here, a couple of other things tripped me up while working through this: The moon's orbital distance was given as 384.399 km on the example form, rather than 384,399. Since all other delimited numbers in the book use commas...

Clarification question: on page 22, under Main Sequence Lifespan, the following callout is made: For Classes Ia, Ib, II, and VI, does this mean they only generate the main sequence lifespan, or should they also determine the subgiant and giant lifespan? For example, if I generate an F6 Ia...

I just spent a long time looking for the "Failed Stars" section, which does not actually exist. I'm assuming the intent on page 219 with regards to Black Holes and White Dwarfs, etc, is to reference the "Dead Stars" section. If that is the case, might I suggest updating the wording on page 219...

Doogie Howser? Incredibly talented individuals can and do happen, even at a young age. Beyond that, what M J said.

I volunteer as tribute! :P

Any chance of an update on this? It's been a couple of months, and the Companion is something I've been looking forward to since picking up the main book.
