How do I find the correct planetary spacing for my red dwarf system?

I have a system with a K6.7V star at 0.585 M☉. The planetary system has 7 orbits --

• A tiny, rocky planet at 0.043 AU with a mass of 0.0465 M⊕.
• A tidally locked, habitable, water world planet at 0.34 AU with a mass of 0.788 M⊕.
• Another rocky planet at 0.64 AU with a mass of
• An asteroid belt at 1.24 AU with a mass of 5.994×10^−4 M⊕.
• A major gas giant at 2.44 AU with a mass of 350.985 M⊕.
• A minor gas giant at 4.84 AU with a mass of 43.143 M⊕.
• And lastly, a small, icy-rocky planet at 9.64 AU with a mass of 0.232 M⊕.

I implemented the spacing factor for this system -- it is the logarithmic spacing between orbits of a solar system. I used our (Earth's) solar system's spacing factor of 0.3, which I don't feel is correct for my system with such a small star.
Additionally, a lot of these masses are extremely rough, and will change. I would like help deciding on the masses, but that probably needs another question to ask.

I'd greatly appreciate any feedback -- even on parts that are not entirely related to the question!! I'm new to this.

• If you don't specify the masses of each body, there is no way you can find any support. Gravity depends on mass and distance.

• The closest planet is too close IMHO and doesn't look like being in orbital resonance with the second one, meaning its orbit is unstable and it's likely to fall to the star. You should refine distances to make your planets have at least some resonance in orbital periods, this would help to ensure your star system is stable enough. Commented May 17 at 11:29
• @L.Dutch I added some temporary masses to give an idea of what I'm looking to achieve. The asteroid belt calculation is from this link. Commented May 17 at 11:48
• @Vesper I see -- I'm using Artifexian's Worldsmith document to calculate my stuff. After chucking in all my data, I got those numbers for the first 7 orbits (I got to choose the distance of the first orbit and the spacing factor based on an inner limit of 0.0061 AU). Commented May 17 at 11:54
