"A Star Is Born"

From Wiki and Wiki

Jackson Maine, a protostellar cloud privately battling gravitational collapse and an alcohol and drug addiction, plays a concert in California to try and lose some excess energy through radiation. His main support is gas pressure Bobby, whose kinetic energy balances out the potential energy of Jackson's internal gravitational force.

After the show, the dust within Jackson becomes heated to temperatures of 60–100 K when he witnesses a performance by Ally, a waitress and singer-songwriter whose particles radiate at wavelengths in the far infrared where Jackson is transparent.

They spend the night speaking to each other, where Ally discloses to him that the dust is mediating his further collapse. Jackson invites Ally to his next phase of contraction. During the collapse she sings on stage with him. Jackson invites Ally to go on tour with him, and his density increases towards the center.

In Arizona, his middle region becomes optically opaque first. Ally and Jackson visit the ranch where his father is buried and where Jackson’s density reaches about 10−13 g /cm3, only to discover that a core region, called the First Hydrostatic Core, has formed where Jackson's collapse is essentially halted.

Angered at this betrayal, Jackson continues to increase in temperature and punches Bobby, who subsequently reveals that Jackson’s core temperature has reached about 2000 K, but the latter was too inebriated to notice.
