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 mearrow_forward
- Match each characteristic below to the appropriate stellar end state. (Select W-White dwarf, N-Neutron star, B-Black hole. If the first is W and the rest N, enter WNNNNNNN). A) Has a mass no greater than 1.4 solar-masses. B) Sometimes appears as a pulsar. C) Size defined by its Schwarzschild radius. D) In a binary system it can explode as a supernova. E) Supported by electron degeneracy pressure. F) Typically about the size of Earth. G) Usually has a very strong magnetic field. H) Viewed from afar, time stops at its event horizon.

- Hey! Please solve this accurate and exact please please it's my important question,I'll thumbs up if it's accurate . Ok thanks.arrow_forwardfor question three can you solve the question directly using the formula N=N0e-t/? given that t1/2=?ln2=0.693? because I cant find it in the textbook of how you plugged in lambdaarrow_forwardPlease solve accurate and exact please please this is impo Please fast!! I'll rate it up if fast and accurate. Thanksarrow_forward
- Please Explain The hotness of stars goes up to millions of degrees Celsius. The coldness of gases can go as low as -273.15 o C. How do you explain the absence of symmetry between hot and cold? Is it possible that there is also a limit to the hotness of any object in the universe? Show your step-by-step solutions.arrow_forward1arrow_forwardHow does one go about these questions?arrow_forward
