Comprehension Questions

What distinguishes a 3+1 system from a 2+2 system?

Correct Choice

A 3+1 system features a triplet orbited by a single star, whereas a 2+2 system consists of two separate binaries orbiting each other.

What is the primary role of the 2+2 system UPM J1040−3551 in research?

Correct Choice

It serves as a cosmic laboratory to help calibrate the age, mass, and composition of brown dwarfs.

Why is the 3+1 configuration considered a 'stress test' for astronomers?

Correct Choice

Because these systems are rare and their stability challenges existing theories of gravitational star formation.

What is a 'brown dwarf'?

Correct Choice

An object too small to sustain hydrogen fusion, often referred to as a failed star.

Which technology was instrumental in identifying the compact TIC 120362137 system?

Correct Choice

NASA’s TESS telescope confirmed by the QUADCOR algorithm.
