| Apr 22 at 15:07 | comment | added | Starfish Prime | @Zadai.Fehbiab brown dwarfs are an excellent place to start if you want lots of large moons. If you search this site for "brown dwarf" you'll find lots of relevant questions and answers, I'm sure. | |
| Apr 22 at 15:02 | comment | added | Zadai.Fehbiab | Actually I'm closer to just inventing my own type of star that fits my needs. The reason of me wanting a big and luminous star is the size of the central planet's hill sphere. Thats because i want to add a number of other moons in the future :) Maybe ill call it... a starfishian-type star ;) | |
| Apr 22 at 15:00 | comment | added | Starfish Prime | @Zadai.Fehbiab your brown dwarf can be sized to generate just the right amount of heat. You have full authorial control, after all. | |
| Apr 22 at 14:58 | comment | added | Zadai.Fehbiab | Thank you again! But won't the brown dwarf heat up a moon this close immensely? | |
| Apr 22 at 14:53 | comment | added | Starfish Prime | @Zadai.Fehbiab the previous author was me, too ;-) You could make the gas giant being orbited a brown dwarf. It is already pretty big at 11 jupiter masses, but crank that up to 50-80 jupiter masses and you can make it pretty warm, though it won't necessarily produce much visible light. | |

| Apr 22 at 12:51 | comment | added | Zadai.Fehbiab | So I've read from the previous author on this thread that a cooler f typ star or a bigger g type star could be ideal for me. Can there be more ways to somehow increase the habitable zone's distance from the star without increasing uv radiation? | |
| Apr 22 at 6:47 | comment | added | Starfish Prime | @Zadai.Fehbiab the issue is that ozone absorbs UV and splits, and the lightweight oxygen radical can reach escape velocity on a suitably warm and low gravity world. Earth isn’t immune, but the process is very slow because the ionization rate is low. A planet around Sirius won’t have that benefit. | |
| Apr 21 at 14:16 | comment | added | Zadai.Fehbiab | Okay, but could there be an extra thick ozone layer or a similar phenomenon that stops some of the ultra short wave radiation coming from let's say a Sirius like star? | |
| Apr 21 at 10:59 | comment | added | Starfish Prime | @Zadai.Fehbiab also, Sirius-A is a main sequence star. Its a binary, sure, but Sirius-A by itself is a perfectly normal hazardously hot and bright star. A cooler F-class star might suit your needs, but so would a slightly larger and brighter G-class. | |
| Apr 21 at 10:52 | comment | added | Starfish Prime | @Zadai.Fehbiab no linebreaks in comments, unfortunately. Remember that a physically bigger star will appear smaller in the sky, because the luminosity of a star scales more quickly than its radius! You can build a sunshade and stick it in a lagrange point for a planet, but that's awkward for a moon unless you build an enormous sunshade. For bigger, hotter stars the problem is the proportion of UV... moving further away reduces the total insolation, but not the proportion of ionizing radiation. | |
| Apr 21 at 7:59 | comment | added | Zadai.Fehbiab | Edit: Sorry i failed to find out how to add line breaks | |
| Apr 21 at 7:57 | comment | added | Zadai.Fehbiab | Thank you for your reply. Sure i could shrink the star. What about an F type star? They are more massive than the sun, but still considered Main Sequence stars. Sirius is an AM star. I'm thinking of maybe 1.5 to 3 times the luminosity of the sun However, I'm opting for a system that's based on the following premise: Bigger star, but this is mitigated by a greater distance and thus less UV-Radiation and heat. Are there any measures i can take in order to reduce the radiation that's incoming and get rid of the jeans escape? I'm also open for scenarios that include artificial measures. | |
