Sounds longer than I remember it being. I feel like events in SciO go by extremely fast. What is actually around an hour feels like 15-20 minutes, if that.

I can't wait to see the test

Anyone have any idea what the topic for next year will be? Will it be mostly the same as this year? I found this:

http://newyorkscioly.org/SOPages/Events.html

But it doesn't say what the topic/focus is unlike some of the other events >.<

I recall hearing in the national supervisor's videos that the focus will shift to the stellar evolution of more massive stars.

Stars of 8+ solar masses go supernova. If their cores are 1.4 to 3.2 solar masses, it becomes a neutron star. If it's at least 3.2 solar masses, it becomes a black hole. Also many neutron stars rotate very quickly and are called pulsars because of the regular radiation pulses.

Yep, I've heard through the grapevine as well that it's going to be stellar evolution with a focus on Type II supernovae and/or high-mass stars - not that there's much difference, since those two kind of go hand in hand anyways.

Looking forward to another (slightly diabolical) test from Cicc at States...

So general consensus is that the topic will shift to focus more on higher-mass stars? Would any of 2012 DSOs stay the same? Anyone know? Thanks in advance :D

DSOs always change.

DSO predictions:
r136a1
Eta Carinae
VY Canis Majoris
Betelguese
A few type II SNR's

Any other ideas?

I am also predicting to see r136a1 on the DSO list and hope that it does.

Yeah that's a hypergiant in the LMC with around 286 solar masses now, and a birth mass believed to be about 360 solar masses right? Also, scientists are not sure how it got that big; above 150 solar masses, protostars should just blow themselves apart (like obese people :P).
