A star spends a 2nd time through the claws of a black hole, astronomers do not come back

Furthermore,

Star spends 2nd time through:

When a star approaches a black hole, she undergoes extreme tide forces. However, The phenomenon, nicknamed “spaghettification”, was popularized by Stephen Hawking in his book A brief history of time. For example, The gravitational forces stretch the star on its axis, until it transforms into a long filament of material.

In theory, this deformation goes as far as complete dislocation. Furthermore, In reality, it all depends on its density. However, NASA recalls that the internal parts of a star are often more compact than its external layers. Furthermore, Some stars can therefore partially resist this type of meeting, depending on their structure.

Simulations led by the Goddard Space Flight Center show that the low stars disintegrate quickly. The densest can be content to lose part of their envelope before leaving. This variability makes each interaction with an unpredictable black hole.

In the case studied here, the first interaction would have withdrawn part of the surface gas. The more compact nucleus would have continued its trajectory without crossing the horizon of events. Two years later, the star would have returned to a similar orbit, again with a very marked light show.

Since April 2019, astronomers have had a real image of a black hole. It was captured by the Event Horizon Telescope, a global network of radiotelescopes. But the interior of the black hole remains inaccessible. On the other hand, this type of disturbance event gives an indirect overview of the forces that are unleashed there. According to NASA, more than 100 of these events have been detected to date in nearby galaxies.
