How can astronomers tell whether there is a second unseen star in a system?
Astronomers can infer the presence of an unseen star in a system through its gravitational influence on the observed star(s). This influence can manifest as deviations in the star's orbit or variations in its brightness or spectral features. Techniques such as astrometry, radial velocity measurements, and gravitational lensing can also be used to detect the presence of unseen stars.
How can astronomers detect a binary star if only one of the two stars is visible from earth?
Astronomers can detect a binary star system, where only one star is visible, by observing the gravitational effects of the unseen companion on the visible star. They can analyze the visible star's motion, such as its changes in velocity or position, which may indicate that it is being influenced by the gravity of the hidden star. Additionally, variations in the visible star's brightness or spectral lines can provide clues about its companion's presence. Techniques like radial velocity measurements and astrometry help confirm the existence of the unseen binary partner.
