I would have went Super Nova on Nova. Damn she's 80 now.

Is it normal in the astronomy community to ignore the light travel issue and talk about things happening 'now'?

We only have two cycles recorded in history, so it's always possible we've got it wrong.

I.e. white dwarf pulls enough matter onto it from larger companion that fusion restarts? Of course, one is a periodic event, and the other most definitely is not. The starting mass of the white dwarf. In order for a type 1a supernova to occur, the mass of the star, with the added gas captured from the neighbor, must become high enough to create fusion in the core via gravitational compression - that is, the white dwarf becomes heavy enough that pressure in the core begins fusion of the Carbon and Oxygen in the core (all the lighter elements were either fused or blown off before the star became a white dwarf). For a normal nova, there isn't enough mass for this to happen, so the hydrogen captured from the companion star instead continues to pile on and heat up until the conditions for fusion are reached in the hydrogen layer. Since Carbon and Oxygen require orders of magnitude more energy to begin to fuse, most white dwarfs will have the hydrogen blanket reach fusion conditions long before the core can, and once the Hydrogen begins fusing, that layer will be rather quickly be mostly eliminated, either by fusion or by being blown off by the energy released. The fusion then stops and the white dwarf begins accumulating hydrogen once again. Mike |

Famed comet hunter and variable lover Leslie Peltier faithfully kept an eye on T CrB for over 25 years, hoping to catch it in outburst. On that fateful February morning in 1946 he'd set his alarm clock for 2:30 a.m., planning to check in on several favorite stars before dawn. But when he awoke and looked out the window, he felt a cold coming on and allowed himself instead to go back to bed. Big mistake. That very morning, T CrB came back to life.
I feel for you Les. Deer stands and natures call is a bitch. |

Quote HistoryOriginally Posted By SixpackinOk: Originally Posted By PanelVanHalen: Originally Posted By kcobean: At the speed of light, time stops. Then is it really a speed? So is time a constant until it hits the speed of light, and then it instantly stops, or does time change with speed until it hits the speed of light? Time and distance are both variable at relativistic speeds. The Lorentz equations describe how much they shrink or slow down at a given speed, compared to an observer at rest. The effect is trivial unless you're going really fast or your clock is really accurate. GPS atomic clocks have to take relativity into account. Of course they're both moving fairly rapidly and their signals are moving deeper into a gravity well. Relativity has something to say about both. Thanks everyone, for distinguishing between Novas and Type IA Supernovae. Interesting that a white dwarf can accumulate mass to bypass the intermediate nova mechanism of surface fusion, and thereby eventually achieve core fusion. I suppose it depends on the speeds and feeds, plus feedstock, if I can borrow the mechanism from machining metal. |
