Answer #1

Diameter of the telescope is d = 260 m

Wavelength of light

The distance of binary star from Earth is

The resolution of the telescope is,

          

Here, is wavelength and d is diameter of the telescope.

It is also defined as, ratio of distance between two binary stars and distance of star from earth.

    

Here, distance between two starts is a, and D is the distance of start from Earth.

Thus,

Therefore, the minimum seperation between two starts is,

=

Radio waves from a star, of wavelength 168 m, reach a radio telescope by two separate paths, as shown in the figure below (not drawn to scale). One is a direct path to the receiver, which is situated on the edge of a cliff by the ocean. The second is by reflection off the water. The first minimum of destructive interference occurs when the star is θ = 26.0° above the horizon. Find the height of the cliff. (Assume no...

Astronomers using a 2.0-m-diameter telescope observe a distant supernova−an exploding star. The telescope's detector records 7.9 × 10−11 J of light energy during the first 10 s. It's known that this type of supernova has a visible-light power output of 6.0 × 1037 W for the first 10 s of the explosion. How distant is the supernova? Give your answer in light years, where one light year is the distance light travels in one year. The speed of light is...

A binary star system is made up of two stars which are 6.25×10^8 km apart and 1050 light years from earth. a) can you see this system as two stars with a 7.8m visible light telescope? (λ=550nm) b) can you see this system as two stars with a radio telescope array with an effective diameter of 3000km? (λ=10cm)

Astronomers have developed a method call interferometry, which uses separate tele- scopes to observe the same object at the same time to achieve very high angular resolution. If astronomers use an interferometer observing the wavelength of 1000 nm to measure the angular diameter of a planet like Jupiter orbiting a star 10 light-years from Earth, how far apart are the telescopes?

Given that the rest wavelength means the wavelength measured in the laboratory (where the low point would be expected), what can be said about the red and blue data lines shown? How is the assumption that the laws of physics are the same everywhere in the Universe relevant here? Why does this suggest a binary star system?

Let's imagine that a new ultra-violet (UV) space telescope has just been launched. It has detected a previously unknown source of UV radiation. The source has a black body spectrum peaking at a wavelength of 82nm, and a flux of 9.4x10^(-20) W/m2. The source seems to be associated with a small red star – perhaps it is a binary companion. If the star and UV source are 100 light-years from Earth, what can you deduce about the UV source? Explain...
