At the end of a massive star’s life, its core can undergo a catastrophic collapse that triggers a supernova explosion. The core remnant consists of about 1.4 solar masses’ worth of pure neutronsand is called a neutron star. What is the approximate radius of such a neutron star, if neutrons arereally like incompressible spheres?
Neutron stars are what are thought to cause pulsars. A pulsar is an astronomical radio sourcethat emits pulses of radiation, as seen from earth. The regularity of the pulses initially causedthe discoverers Jocelyn Bell Burnell and Antony Hewish to speculate that the signals were fromanother civilization. The pulses were so regularly spaced that it was thought that pulsars couldbe used as a time standard. However, it was soon seen that the rate of pulse emission slows, butthen abruptly increases in events known as glitches. The current model (highly simplified) for a pulsar is a neutron star, one in which the electronshave been pushed down into the nucleuses by extreme gravitational forces to combine with theprotons to form neutrons. Material falling onto the surface of the neutron star gets superheatedand shoots off in the form of a jet. If the jet doesn’t coincide with the rotational axis of the star,the jet will precess around the axis. If the earth happens to lie on the cone of…
A.1You are on an interstellar mission from the Earth to the 8.7 light-years distant star Sirius. Yourspaceship can travel with 70% the speed of light and has a cylindrical shape with a diameter of6 m at the front surface and a length of 25 m. You have to cross the interstellar medium with anapproximated density of 1 hydrogen atom/m3.(a) Calculate the time it takes your spaceship to reach Sirius.(b) Determine the mass of interstellar gas that collides with your spaceship during the mission.Note: Use 1.673 × 10−27 kg as proton mass.
A.2Because you are moving with an enormous speed, your mission from the previous problem A.1will be influenced by the effects of time dilation described by special relativity: Your spaceshiplaunches in June 2020 and returns back to Earth directly after arriving at Sirius.(a) How many years will have passed from your perspective?(b) At which Earth date (year and month) will you arrive back to Earth?
