The small dense remains of a high mass star are either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are formed from the core collapse of a massive star and are incredibly dense, composed mainly of neutrons. Black holes are formed when the core collapse results in a singularity with infinite density and a gravitational pull so strong that not even light can escape.
Neutron star
The remains of a high mass star could be a neutron star or a black hole, depending on the mass of the original star. Neutron stars are extremely dense and compact objects, while black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape.
A supergiant star can explode into a supernova, where the outer layers are ejected into space. What remains may collapse into a neutron star or black hole, depending on the mass of the original star.
A black hole is formed when the remains of a massive star collapse under their own gravity, creating a region of spacetime where gravity is so strong that not even light can escape. The mass is concentrated into a small volume called the singularity at the center of the black hole, surrounded by an event horizon beyond which nothing can escape.

A T Tauri star is sort of a precursor of a star, or about to become a "real" star. Therefore, it can last anywhere from a few million to several trillion years before it runs out of energy, depending on its mass.
Precursor
A neutron star is already the remains of a massive star that has run out of fuel.

The precursor of basophils is the basophil progenitor cell, the precursor of monoblasts is the monoblast cell, the precursor of lymphoblasts is the lymphoblast cell, the precursor of megakaryoblasts is the megakaryoblast cell, and the precursor of myeloblasts is the myeloblast cell. These precursor cells undergo differentiation and maturation processes to become fully functional mature blood cells.
