- The time it takes for a cloud 106,000 AU in radius to collapse in "free-tall to form a new star is half the time it would take for an object to orbit the star on an extremely elliptical orbit with a semimajor axis of 53,000 AU (half the 106.000 AU radius). Part A Use Kepler's third law to find the collapse time, assuming the star has the same mass as the Sun. Express your answer in years to two significant figures.

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_forwardState the definition for a parsec, and derive its value in terms of As- tronomical Units.

- Please do not give solution in image formate thanku 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.

- Which of the following most correctly explains why we have not yet observed any white dwarfs derived from M stars: Group of answer choices Most M stars end up as neutron stars or black holes. The lifetime of M stars is longer than the age of the universe. Most M stars are located near the edge of the universe, beyond the visible horizon. Most M stars are members of a binary system, and the white dwarf would be obscured by the glare of the more massive companion. White dwarfs are too dim to be observed with currently available techniques.arrow_forwardAnalyze the multi-wavelength images below and answer the few questions that follows up : 1.

Where are the old stars? What colour do they have? Are they visible in any image? Why?arrow_forwardChoose the correct statements from the following list referring to white dwarfs. (Give ALL correct answers, i.e., B, AC, BCD...) A) The pressure that balances gravity in a white dwarf is called degenerate electron pressure. B) The power source of white dwarfs is left-over heat. C) White dwarfs cool slowly because they are small and eventually fade-out to become black dwarfs. D) White dwarfs with mass greater than 1.4 times the Sun's mass cannot exist. E) Stars with a mass like the Sun will end up as a white dwarf star. F) White dwarfs are less dense than red giants. G) White dwarfs are the coolest main sequence stars.arrow_forward
- 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.arrow_forwarda) Sketch a generic HR diagram, including labels for the axes. (Take a picture or scan your work and upload it as a separate file.) b) Consider the following three stars, place them on your HR diagram and determine their rough spectral type and class of star. Also calculate their size relative to the Sun. I) L = 0.001 Lsun T = 3000~K II) L = 20,000 Lsun T = 4000K III) L = 0.001 Lsun T = 15,000Karrow_forwardHigh Mass Stars Problem 4. Black Holes The Schwarzschild radius determines the event horizon of a black hole. Construct the equation defining this radius using the fact that the escape velocity at this radius is c (the speed of light). Use M for the black hole mass and RS for the Schwarzchild radius.
