Most Population III Supernovae are Duds
Robert L. Kurucz
One Population III dud supernova produces enough oxygen to enable ten million solar masses of primordial gas to bind into M dwarfs. This is possible because radiation from other Po…
Astrobiology in the Environments of Main-Sequence Stars: Effects of Photospheric Radiation
M. Cuntz, L. Gurdemir, E. F. Guinan +1
We explore if carbon-based macromolecules (such as DNA) in the environments of stars other than the Sun are able to survive the effects of photospheric stellar radiation, such as U…
Astrobiological Effects of F, G, K and M Main-Sequence Stars
M. Cuntz, L. Gurdemir, E. F. Guinan +1
We focus on the astrobiological effects of photospheric radiation produced by main-sequence stars of spectral types F, G, K, and M. The photospheric radiation is represented by usi…
Cryptoplanet update
Robert L. Kurucz
We have had several talks recently reviewing 11 years of exoplanet discoveries through radial velocity variations, or from transits, or from microlensing. More than 200 exoplanets…
The precession of Mercury and the deflection of starlight by special relativity alone
Robert L. Kurucz
I show that the precession of the orbit of Mercury and the deflection of starlight by the Sun are effects of special relativity alone when the gravitational field of a particle is…
Elementary Physics in the Cellular Automaton Universe
Robert L. Kurucz
General relativity is a mathematical model that uses sophisticated geometry to describe simple physics. It agrees with experiment in the few tests that can be made, but the whole e…
