Professor Zumwalt was excited to be working with her fourth years. It was the last semester she'd have them in class, and they were learning vital information about stars that would assist them in their OWLs and future studies.
“Welcome back to another year! This year will be our last together before you move back to studying with Professor Harrington," she said, knowing that this was one of the last classes to have actually had the woman prior to Adorah. "I hope you all are ready because we've got a lot to learn this semester, and we're jumping right in!” Adorah said, noticing some of the students rolling their eyes, but others looked excited to learn more. She set up the projector with a wave of her wand so images of the stars they discussed would be visible on the board.

Protostar: a contracting mass of gas that represents an early stage in the formation of a star. These are formed in great clouds of gas and elements. Before the star begins to produce magical essence, it is considered a protostar, meaning it is not fully burning bright as it will in a few thousand years.
Binary Stars: two stars orbiting a common center of mass. The brighter star is referred to as the primary star (A) and the other secondary cool:. Most stars visible in the night sky have a secondary companion, and some cases have multiple. Somewhere between one-third to one-half of all stars are binary stars. The star Sirius is a binary star being orbited by a smaller white dwarf.
Dwarf Stars: any star of average or low luminosity, mass, and size.
Brown Dwarf Stars: stars that did not have enough gas/mass put into them to burn and they quickly radiate out their heat and become much cooler. Some brown dwarfs are quite similar in size to Jupiter, but their formation is different, and despite being very similar gas giants in the sky, they are classed as different objects.
White Dwarf Stars: also called degenerate dwarf, is a stellar core remnant that is very dense.
Eventually, they will all become black dwarfs which are non-luminous dead stars.

Finishing the lecture, Adorah smiled at her students. Most of them were still awake, although one was nodding off every few seconds in the back. “We will stop here and continue our discussion on types of stars next week,” she said. She'd ended the lesson a little earlier than expected, but she also wanted to make sure students were paying attention when she delivered important information. “No homework this week, but I want you all to make sure you’re reading your textbook and the chapter about the stars we discussed today,” Adorah finished, dismissing the students.
