Neutron Stars: The Collapsed Core of Massive Stars
An average neutron star is about 1.4 times as massive as the Sun but they measure only around 19 to 27 km (12 to 17 miles) in diameter or just about the size of Manhattan Island. How Dense Is a Neutron Star? Imagine squishing …

Because observations at X-ray, infrared, and radio limit the size of the object to smaller than 10 AU.

Massive Compact Halo Objects
If some of those objects are MACHOs, their energy can be interact with the stars of the cluster. According to [3], when a range of masses is present interactions lead to mass segregation where the most massive bodies have the most spatially compact distribution, leading to less massive objects, on average, to have a less compact distribution.

Example 1: Extreme gravity. In this section, you were introduced to some very dense objects. How would those objects' gravity affect you? Recall that the force of gravity, F, between two bodies is calculated as where G is the gravitational constant, 6.67 × 10 –11 Nm 2 /kg 2, M 1 and M 2 are the masses of the two bodies, and R is their separation. Also, from Newton's second law,

How to detect if an Object is being crushed
Asumming we're dealing only with linear velocities, there are two forces to consider for each contact: 1) weight 2) impact force. Weight is caused by gravity and you can directly calculate it via second Newton's law: F_weight = m * g However you're only interested in normal component of this force at the contact point so you'll need to project it to receiving body's normal vector at the ...

Lam's team reports a slightly lower mass range, meaning that the object may be either a neutron star or a black hole. They estimate that the mass of the invisible compact object is between 1.6 and 4.4 times that of the Sun. At the high end of this range the object would be a black hole; at the low end, it would be a neutron star.
