We will have our final seminar meeting of the semester this Friday at 2:00 pm on Friday in the math seminar room, during which we'll finish up our discussion of stellar winds. I will be bringing the snack again this week.

Office hours this week are: Monday 1 to 3:30, Tuesday and Wednesday 3:00 to 5:30 pm, both days, and let me know if you'd like to meet on Thursday, but for now, no official office hours are scheduled.

Read the fourteenth assignment [pdf] and think about the material, go over last week's problems and solutions, and prepare to discuss the first four-plus-one pages of Owocki's Radiation Driven Stellar Winds from Hot Stars [pdf].
