Re: Astronomy C
Can anyone interpret the "Motions" portion of the Astronomy C rules?

If you could provide some context (just a few words, don't want you to get in trouble for copyright stuff) I could try to help.windu34 wrote:Can anyone interpret the "Motions" portion of the Astronomy C rules?
However (this is a complete guess, as I haven't seen any rules), maybe it means the motion of stars in a binary (or more) system? Type Ia supernovae need 2+ stars, so there's bound to be a lot of stuff about binary star systems, especially RV curves, astrometry, etc.

Re: Astronomy C
It asks you to use information such as motions to answer questions relating to this year's topics and the DSOs.Adi1008 wrote:If you could provide some context (just a few words, don't want you to get in trouble for copyright stuff) I could try to help.windu34 wrote:Can anyone interpret the "Motions" portion of the Astronomy C rules?

Re: Astronomy C
Would some kind person with the rules post the DSO list? Thank you!
Also Windu, motion problems usually refer to math, specifically Kepler's laws of planetary motion. Try looking at previous tests for examples; that part of the rules doesn't change much.

Re: Astronomy C
Okay...as always, this is just my understanding of the rules; nothing official. I'd say it'll have to do with binary star systems and their motion (RV, astrometry, using Kepler's Laws etc), using them to find the period of the system, combined mass, etc as said before, and using Hubble's Law to calculate distances to Type Ia supernovae (since SNe Ia are really far, they'll be receding really quickly as per Hubble's Law!!). Those are really the only "motions" I can think of associated with Type Ia supernovae specifically.windu34 wrote:It asks you to use information such as motions to answer questions relating to this year's topics and the DSOs.Adi1008 wrote:If you could provide some context (just a few words, don't want you to get in trouble for copyright stuff) I could try to help.windu34 wrote:Can anyone interpret the "Motions" portion of the Astronomy C rules?

Re: Astronomy C
I've been looking for information about Henize 2-248, which is on the official list. However, all I found was information about Henize 2-428. Are these DSOs equivalent?

Re: Astronomy C
It's probably a typo, especially since 2-428 is related to this year's topic. I'm pretty sure there isn't even a 2-248.antoine_ego wrote:I've been looking for information about Henize 2-248, which is on the official list.
