What is a binary star system in which one star periodically blocks the light from another?
That's an 'eclipsing binary'.
The process of one body in space blocking light from another?
This phenomenon is known as an occultation, where a celestial body passes in front of and blocks the light from another body, such as a planet or star. It can be used to study the atmosphere, structure, and characteristics of both objects involved. Scientists can measure the timing, duration, and changes in light during occultations to gather valuable information about the bodies involved.
What is a heavenly body with periodically changing luminosity?
Variable star
A star whose luminosity varies periodically is a?
Periodic variable.
Which object would best be identified by a periodic Doppler shift in a star's spectrum along with a dip in the star's light intensisty?
An exoplanet would best be identified by a periodic Doppler shift in a star's spectrum, known as the radial velocity method, along with a dip in the star's light intensity, indicating a planetary transit. When an exoplanet orbits its star, it causes a detectable Doppler shift in the star's light due to its gravitational pull and blocks a portion of the star's light when it transits in front of it.
What is the process of one body in space blocking light from another one?
When the moon blocks the sun's light, or the Earth blocks the light from the sun that strikes the moon, it's called an eclipse. For an arbitrary body passing in front of another one, the term astronomers usually use is "occultation".
A star system in which on star blocks the light from another is called?
"Occulting binary". The word "occult" means hidden or in shadows; if a binary star's orbital plane happens to be exactly through the Earth's path, we might see two stars when they're separate and then see one of the stars disappear behind (or in front of) the other.
What causes a star to dim every 3 days?
A star that dims every three days would likely be a binary star system. Such a system consists of two stars that orbit their mutual center of mass. If their orientation is right then, from out perspective, one star will periodically block the other from view, reducing the amount of light we see from them.
Is Star Wars the most popular theme for Lego building blocks?
Star Wars themed Lego blocks have been sold since 1999 and continues to be the most popular theme of Lego blocks as said by many consumers and reviewers.
If light from one star is 40times more intense than light from another star what is their difference in magnitudes?
The magnitude difference between the two stars is 2.5 * log(40) = 4.0 magnitudes.
What magnitude of a star is how bright it would be at a distance of 32.6 light years from earth?
That is called the absolute magnitude. It is a measure of the star's real brightness. Apart from the distance (10 parsec), another (implicit) assumption is that there is nothing in between that reduces the star's light.
How can astronomers tell if a star may have a planet revolving around it?
There are two ways you can tell if a star may have a planet around it. One way is that the star would have a slight wobble in its motion across our sky. This is caused by the planet's gravitational pull on the star which would cause a slight movement or shift in its alignment. More easily detectable by modern telescopes would be a periodic reduction in the level of light coming from the star. The key is the period in which the light reduction occurs, which would offer a clue as to the period of the orbit of the planet around the star as it blocks light during its orbit.
