Um, dust, little grains of rock and metal within the disk, collided with each other and stuck together. And this process sort of snowballed over millions of years until the chunks grew into mini-planets, proto-planets. Professor: Yes. This process is called accretion, and we call the disk...
MALE PROFESSOR: Yeah. This process is called accretion.And we call the disk an accretion disk.Now ...think of it as two parts—an inner accretion disk and an outer accretion disk.In the inner part, once an object gets large enough, that object's gravitational field gets stronger, which ...

<italic>Context. </italic>The role of low ionization nuclear emission region (LINER) galaxies within the picture of active galactic nuclei (AGN) has been controversial. It is still not clear whether they host an AGN in a low accretion mode or whether the
The name originated from Nawa'a Napoleon, an associate professor of Hawaiian Language at Kapiolani Community College. It honors the Polynesian sailors using "heavenly knowledge" navigating the Pacific Ocean, reminding us that romance is still alive and well in space and astronomy. Laniakea is ...

What Are Fast Radio Bursts or FRBs and How Do We Find More? What Are Stellar-Mass and Intermediate-Mass Black Holes? What Are Some Objects That Challenge the Definition of Pulsars? What Have We Learned From Neutron Stars Interacting With Their Environment?
(Accretion is the process by which matter is fed to a celestial body, like a star, white dwarf, neutron star or black hole.) Detached binaries are binary stars that do not exchange material. Semidetached binaries are stars in which some material flows from one star to the other. And ...
Much of my work has been to show how to understand the connection between jets and black hole spin. The key takeaway point is that in addition to magnetic fields and high or low black hole spin, counter-rotation/co-rotation between black hole and accretion disk is fundamental. What can ...
