When a star collapses to half size what does the gravitational field at its surface do?
When a star collapses to half its size, its gravitational field at the surface increases. This is because the gravitational force is directly proportional to the mass of the star and inversely proportional to the square of the distance from the center of the object. As the star collapses, its mass remains the same but the distance to its center decreases, leading to a stronger gravitational field at its surface.
You can measuring the altitude of a star by measuring the angle between your horizon and the star using a?
We would typically use a sextant to measure the angle of a star above the horizon.
How to find the diameter of a star?
To find the diameter of a star, scientists use a method called interferometry. This involves combining data from multiple telescopes to create a detailed image of the star's surface. By measuring the angular size of the star and its distance from Earth, astronomers can calculate its diameter.
Can A planet's mass can be determined by observing it transit a star?
Yes, a planet's mass can be determined by observing its transit across a star. By measuring the dip in the star's brightness during the transit, astronomers can calculate the size of the planet and its gravitational effect on the star, which provides information on the planet's mass.
How did they now Goldilocks is a planet?
A "Goldilocks planet" is ANY planet that orbits its star at a distance from that star where the heat from the star means that any water present on the planet is in liquid form. This can be determined by measuring the stars temperature (its size and colour) and observing the planets orbital distance.
What is the gravitational field strength of Betelgeuse?
The gravitational field strength of Betelgeuse, a red supergiant star, is much higher than that of Earth due to its massive size and density. However, it would vary depending on the distance from the star and the specific location around it.
How do you know the sun is a typical star?
Through measuring how much luminosity it is giving out, measuring the size of the star, and find out how hot the star is, we can categorize each star in a graph. Our sun just happens to be part of the main sequence of stars; the sun is not as big as a giant or a super giant star nor is it as small as a white dwarf so therefore the sun is in between. Main sequence stars are more common because they are very stable so it wont change over a long course of time, unlike variable stars, which changes its size and luminosity. A variable star has a period of a day to a month. A period is how long it takes for the star to return to its starting point as it changes in a cycle.

Who was the star of TV show gidget?
Sally Field was the TV Gidget.
Can the mass of a planet be determined by observing it transit a star?
Yes, the mass of a planet can be determined by observing its transit across a star. By measuring the duration and depth of the transit, scientists can calculate the planet's size and mass based on the gravitational influence it exerts on the star. This method is known as the transit method and is commonly used in exoplanet studies.
