Q:
You’ve just discovered another new X-ray binary, which we will call Hyp-X2 (“Hyp” for hypothetical). The system Hyp-X2 contains a bright, G2 main-sequence star orbiting an unseen companion. The separation of the stars is estimated to be 12 million kilometers, and the orbital period of the visible star is 5 days.
Use Newton’s version of Kepler’s third law to calculate the sum of the masses of the two stars in the system.
a)Express your answer in kilograms to two significant figures.
b) Give your answer from the previous part in solar masses. ( Msun= 2.0 x 10 /30 kg). Express your answer as a multiple of sun’s mass to two significant figures.
C) Determine the mass of the unseen companion. ( Hint: A G2 main-sequence star has a mass of 1 Msun.) Express your answer as a multiple of sun’s mass to two significant figures.
The previous answer was not correct, please help me
Read all the instructions carefully then answer. Kindly give me a detailed answer in a clear handwriting of the subparts ,e,f and g by mentioning the subpart's name. It is one whole question. All the subparts are related. Take your time solving this. I am attaching the full question but I only need e,f and g (in details). All the questions are related. This is my fourth time uploading these questions as I got wrong answers previously. So kindly answer this one by following the given instructions. I am strictly forbading to give the answers of subpart a and b. This is my fourth time uploading this question and everytime you are giving me answers of a,b and c. I will upvote if the answer is correct. Thank you.
State the definition for a parsec, and derive its value in terms of As- tronomical Units. Convert your answer for the value of the distance of a parsec in Astronomical Units into light years. Be sure to include a large and clearly labeled diagram showing how you arrived at your conclusions. Be sure to show all work!

A) On the main sequence, more massive stars are colder. B) High mass stars are the most numerous type of stars observed in the galaxy. C) Giants are colder than main sequence stars at the same luminosity. D) Giants are brighter than dwarfs at the same temperature. E) On the main sequence, more massive stars are dimmer. F) White dwarf stars are much denser than main sequence stars. Hint: White dwarf stars have about the mass of our sun, but are only the size of the Earth. Therefore, they have a very high density.arrow_forward

- a) The star 58 Eridani is a feint but naked-eye star similar to the Sun. Suppose that you are observing this star in the night sky without a telescope. Ignoring any interstellar extinction or atmospheric absorption, approximately how many photons per second arrive at your retina? Show all steps in your calculation. Look up any required information about the star using Wikipedia. Use sensible approximations so your calculation is straightforward. For example you could consider only the region of the spectrum where the photon flux peaks. b) The Mid-Infrared Instrument (MIRI, camera and spectrograph) on the James Webb Space Telescope operates in the band 5 – 28 µm. For 58 Eridani, approximately how many photons per second can be used by this instrument? Assume that MIRI takes all the photons from the full JWST mirror. Show all steps in your calculation. Describe briefly two or three other factors which play a role in determining the sensitivity of an instrument such as MIRI?arrow_forwardWrite a CR for the solved problem. A example of one is attached as well. The problem about the ROCK is the example CR. The problem you ARE writing a CR for is 5x^2-8x=3. Instructions below. For the CR's, claim you should answer the question of , do you get 2 real solutions, 1 real solution, or 2 complex solutions? For your reasoning you should explain how you know. Use the example attached to help you answer. hints: that plus minus sign means there are two answers. If the number under the square root is positive, you have two real solutions. If the number is negative you have two complex solutions. If the number is 0 under the square root you have 1 real number solution.arrow_forwardPart A What was the distance between the points that would someday become, respectively, the center of the Milky Way Galaxy and the center of the Virgo Cluster at the time of decoupling?
