Contineo, using Luminosity, AbsMagn and AppMagn simultaneously is redundant. They all define the star's luminosity, so you must use only one of these quantities. SE simply ignores AbsMagn and AppMagn if Luminosity is present, ignores AppMagn if AbsMagn is present and Luminosity is not, and uses AppMagn and Dist to calculate luminosity, if Luminosity and AbsMagn are not present.
Contineo, inclination of orbit of 55 CnC A and B is real, or some random number? If it random, I suggest to change it to something near 50-55°, to make binary star orbits complanar to 55 CnC A planetary system. Hubble has measured inclination of 55 CnC d (53°), and 55 CnC e is transit planet with inclination of 81°. So we might expect that inclinations of other planets in the system must be near that range, probably closer to 53°. I have modified script for other planets to make them have inclination of 53°, and calculated real masses as M = Mmin / sin i.
Code
Planet "55 Cnc b" { ParentBody "55 Cnc A" Mass 318.04 // assumed i = 53, M sin i = 254.56 Orbit { Epoch 2453035 Period 0.04011310962 SemiMajorAxis 0.1134 Eccentricity 0.0159 Inclination 53 // 55 Cnc d ArgOfPericen 164 } }
Planet "55 Cnc c" { ParentBody "55 Cnc A" Mass 65.6481 // assumed i = 53, M sin i = 53.7758 Orbit { Epoch 2449989.339 Period 0.1214114942 SemiMajorAxis 0.2403 Eccentricity 0.053 Inclination 53 // 55 Cnc d ArgOfPericen 57.4 } }
Planet "55 Cnc d" { ParentBody "55 Cnc A" Mass 1613.274 // real mass, M sin i = 1220.297 Orbit { Epoch 2452500.6 Period 14.28641089 SemiMajorAxis 5.76 Eccentricity 0.025 Inclination 53 // Measured by Hubble ArgOfPericen 181.3 } }
Planet "55 Cnc e" { ParentBody "55 Cnc A" Mass 8.36866 // real mass Radius 13869.448 Orbit { Epoch 2449999.836 Period 0.002016596167 SemiMajorAxis 0.0156 Eccentricity 0.06 Inclination 81 // Transit detected ArgOfPericen 170 } }
Planet "55 Cnc f" { ParentBody "55 Cnc A" Mass 57.3739 // assumed i = 53, M sin i = 45.8208 Orbit { Epoch 2450080.911 Period 0.7137729628 SemiMajorAxis 0.781 Eccentricity 0.0002 Inclination 53 // 55 Cnc d ArgOfPericen 205 } }
The "ParentBody" parameter on the catlong 55 Cnc planets would need too be modified to "55 Cnc A" instead of just "55 Cnc" Here's the modification below.
The planets should also have the A before their letter designation. Ex: 55 Cnc Af

Hi, once again. I was hoping someone could point out an error for me. I've been working on the 40 Eridani System. Yet again, another single obstacle is preventing it's completion. Here are the scripts.
Code
StarBarycenter "Keid/OMI2 Eri/40 Eri/Gliese 166/HIP 19849/HD 26965" { RA 04 15 16.32 Dec -07 39 10.34 Dist 5.044 }
Code
Star "Keid A/OMI2 Eri A/40 Eri A/HIP 19849 A/Hip 19849 A/HD 26965 A" { ParentBody "Keid/OMI2 Eri/40 Eri/Gliese 166/HIP 19849/HD 26965" Class "K1 V" Mass 0.77346 Radius 1097939 Luminosity 0.28963 //AbsMagn 6.17 //AppMagn 4.43 Age 5.6 // 7.936
For some reason, the white drawf star, Keid B is being displayed as the same spectral type of Keid A; an orange dwarf. I can't seem to fix this problem. Can anyone help?

Keid B is Class DA. I'm no SE expert, but the engine is probably defaulting on the first star and ignoring the DA as it is invalid input.

Sorry. I was just trying to be helpful and I saw that didn't seem to fit with what I read about the star scripts.

Keid B is a simple "DA" WHite dwarf as described in the script. I don't know why in Space Engine it's being displayed as a K1 orange dwarf. It's so annoying.

Do you select a Keid B itself or the entire system? Then selected a system, SE displays its brightest component's class as the entire system class.
