How do the orbits of star systems V871 Centauri (septuple), Gamma Cassiopeiae (octuple), and QZ Carinae (nonuple) work?
Several years ago, I asked the question on here, "How do the orbits of Nu Scorpii and AR Cassiopeiae work?" At the time, these two stellar systems were the most populated (I don't know the ...

What happens if supernova undergoes in tightly close multi stars system
I do wonder in a tight or close orbital binary stars or multi stars system, if one stars undergoes supernova and that blast can lead another stars in the system to become supernova, too?
Is there ...

How likely are triple planet systems?
Is it likely to ever discover three planets of similar mass revolving around a common barycenter, or would such a system be too unstable? Such triple planet system would look like a triangle once in a ...

Is it correct to say that only binary and solitary star systems are stable?
Recently it has been shown that a large number of binary stellar systems exist. It seems to me that the orbits of stars in systems containing three or more stars will inevitably be chaotic, resulting ...

Relation between inner and outer eccentricities in a hierarchical triple star system
According to Table 3 of Sterzik & Tokovinin (2002), the inner eccentricity of a triple star system (i.e. the eccentricity of the inner binary) is, most of the times (70%), larger than the outer ...

Origin as binaries and multiple system
The majority of hot stars originate as binaries or multiple systems. How is it with the cooler spectral types? Are they usually born as single stars?

Is a double quasi-binary system valid?
I was messing around with 4-body problems, and discovered a system where a close binary and a regular binary pair orbit each other. The regular binary gets disrupted every few orbits and one star ...

Is there any planet or black hole where we could experience time dilation like in the movie Interstellar?
As we seen in Interstellar movie Copper goes to a planet where he experienced time dilation which was 1 hour of staying on that planet will cost the 7 years on the earth. So, is there any planet or ...

Naming convention for multiple star systems
Okay, so I've seen different notations for the stars in β Capricorni. Some sources state that the stars are Aa, Ab1 and Ab2, Ba, and Bb, while others say that they are Aa, Aba and Abb, Ba, and Bb. So, ...

Calculate the absolute magnitude for a multi-star system
We know that the absolute magnitude of a single star can be calculated with the formulae:
$$M_{\rm bol} = 4.75 -2.5 \log_{10} \left(\frac{L_*}{L_{\odot}}\right)\ ,$$
$$M = -2.5 \log_{10}(L_* / L_0),$$...

Are the orbits of all triple star systems at least technically unstable?
Background:
In the Circular Restricted Three Body Problem (CR3BP, CRTBP) some halo orbits are mathematically stable. That means that the orbit of the third body is closed, periodic, and stable ...

Which star system has the highest multiplicity (# of stars), whose orbits are known for all stars?
I posed a question on here a couple months or so ago about the orbital patterns of each of the seven stars in the two septuple star systems Nu Scorpii and AR Cassiopeiae. It went unanswered for more ...
