The End of Massive Stars

The evolution of our Sun from ordinary star into red giant is radically different from the evolution of much more massive stars towards their end-points: supernova explosions followed by black holes.
This lecture will contrast the relevant nuclear physics and thermodynamics that determine these very different outcomes.
A lecture by Katherine Blundell OBE recorded on 18 January 2023 at David Game College, London.

I have been waiting (what seems like forever) for this new lecture. Thank you! Always amazing video lectures. 👋 from 🇨🇦

[@lilysceejeanmoonlight]

Brilliant explanations on uncommonly spoken about subjects. Wonderful 👍😊

I have been studying neutrinos for a little while now 12mths and the more i dig the more fascinating i find these massless slippery little suckers! Gorjezz!

That was an amazing walk-through of why the Hertzsprung-Russell diagram is the way it is (and certainly crystallized the concepts for me). If I ever have to explain it to anyone else, I'll just show them that segment of this lecture.

Lovely lecture. Many thanks.

Thanks for posting this !

If you like these lectures you might like older Gresham lectures by Carolin Crawford.

absolutely!

Yay, I actually Recognized Dr. Blundell by voice. (not visually impaired - just a musician)

Excellent lecture, but it didn't cover at all what I thought it would, based on my reading of the title. I took it as possibly meaning the end of ALL massive stars, as this is a condition the Universe is generally heading toward. Over time, all the bright, massive stars die out, leaving a bunch of milquetoast remnants. (There will occasionally be large stars formed anew, but that will be increasingly rare.) But I suppose I shouldn't deride such milquetoast too much, as any intelligent beings, in the far future, may have to huddle around them. It's just that they won't have a sky filled with the kinds of spectacles we now enjoy.

It was chilly in Chile

1987a shows how ludicrously luminous 30 doradus is - o, to see r136a1 pop! 🌃🌟🌁

[@lilysceejeanmoonlight]

Beautiful linguistics!

[@richardverghese1353]

does dark matter have any influence on star formation ie a single star ?

[@carolinshining-warner2020]

Please fix the mic

[@vapeymcvape5000]

What's the deal with the mic noises? As much as I love Katherine's lectures, I'm going to have to turn this off.

What is String Theoretical Vibration analysis of e-Pi-i omnidirectional-dimensional logarithmic condensation at Singularity-point reciprocation-recirculation positioning, how are the Tensor Resonance Fusion-Fission Function bonding relative-timing proportioning of harmonic phase-locked 2-ness conditions maintained in floating point line-of-sight superposition identification by Mathematical Musical Measurement related to the mass-energy-momentum states of Stars, and why is this the combination of Dirac's large number reciprocal connection concepts merged with Susskind's holographic time-timing prime-cofactor frequency density-intensity alignment at Black Hole Horizons. Model orthogonal-normal dimensionality stage levels of superimposed frequency-amplitudes as Newton did in the rainbow effect of prisms splitting and recombination.., that is what the Fusion-Fission Function tuning of elemental Quantum-field Condensates in the general resonances of Galaxies is doing in the "dinner plate" disc of Stars and projected transverse Sublimation-Tunnelling jumps of Singularity-point nodal-vibrational tuning. Superposition Totality is self-defining coherence-cohesion objective, Eternity-now Interval in/of QM-TIME Completeness. Big job to disassemble and elaborate why e-Pi-i sync-duration is entangled 1-0-infinity is Galileo's instantaneous recognition of harmonic measures, for example. We all have direct access to our Mind-Body Memory Code "Palace", self-defining hyper-hypo logarithmic trancendence modulation cause-effect mechanism of sense-in-common. ..supposed to work it out for yourself..

at least it is not the end to massive sandwiches! (I hope) Cheers
