Usually, if the initial fetal heart rate and contraction pattern show that both mom and baby are doing well, the monitor is removed and used intermittently. If there are no indications for continuous fetal monitoring, it is OK to ask the nurse to remove the monitor to allow you to walk.
A star forms a nebula when it runs out of fuel. The star either  becomes a red giant or a supergiant, then the star would be blown  off into space either by expansion or expâ¦losion. The outer layers,  which was released into space, would become a nebula, or sometimes  a part of a larger nebula.
Massive stars form in the same way as low mass stars--they just form more quickly because there is more mass to speed-up the process. Whereas the Sun took about 50 million years to contract from a cold gas cloud to a main sequence star, a star with 15 solar masses collapses to the main sequence in 60,000 years.
