A star that consumes hydrogen to form helium is called a "main-sequence" star for all the time it is a hydrogen-fusing object. When it uses up all its fuel, the core contracts because the outward radiation pressure is no longer enough to balance the gravitational force. The core temperatur...
It is also known that moleculargas is dominated in circumnuclear regions in the luminous starburst mergers;i.e., $\\Sigma$(gas) $\\simeq \\Sigma$(H$_2$). Therefore, the above relationshipsuggests a star formation law; $\\Sigma$(SFR) $\\propto \\Sigma$(gas). We suggestthat this ...
A star delta starter begins with the motor’s stator winding connected in star formation. Upon reaching about 80% of its full load speed, the motor transitions to a delta-connected stator winding. A star delta starter is a type of reduced voltage starter. We use it to reduce the starting...
The end result is a star whose mass is 90% neutrons, which can't be squeezed any tighter, and therefore the neutron star can't break down any further. Characteristics of a neutron star Astronomers first theorized about the existence of these bizarre stellar entities in the 1930s, shortly ...
notation, i.e.,\({[X]}=\log {X_{\mathrm{star}}} -\log {X_\odot }\)for any abundance quantity X, and\(\log {\epsilon (X)} = \log {N_{{X}}/N_{\mathrm{H}}} + 12.0\)for absolute number density abundances. For helium, we use Y, that is the fraction of He in ...

What is the true shape of the universe? A flat universe has Euclidean geometry, and the simplest shape it can adopt is that of a sheet. There are also other, more complex shapes that a flat universe could have, such as a "3-torus." ...
