Expected Number of Neutron Stars in UFDs

I sample a Salpeter IMF using the method of inverse transform sampling. Starting with the integral of the Salpeter IMF, N(< M) ∼ M^-1.35, I construct the normalized cumulative distribution function (CDF) by computing (M^-1.35 – M_1^-1.35) / (M_2^-1.35 – M_1^-1.35) for 10,000 masses M evenly spaced in log between the integration limits M_1 and M_2. 127 more words

Top 10 Stars That’ll Blow Your Mind

No one can help but look at all the stars which adorn our skies and wonder, “what’s out there?” It’s natural to dream about that which lies so very beyond our reach. 2,162 more words

Astronomers closer to proving gravitational waves with precise measurements of rapidly rotating neutron star

When Albert Einstein proposed the existence of gravitational waves as part of his theory of relativity, he set in train a pursuit for knowledge that continues nearly a century later. 588 more words

Meet the Cosmic Tootsie Pop

Astronomers have found some pretty strange objects lurking deep in the universe — voracious black holes more massive than a billion suns, lonely planets wandering among the stars, galaxies made almost entirely of dark matter, and more. 721 more words

Astronomers discover first Thorne-Zytkow object, a bizarre type of hybrid star

via Astronomers discover first Thorne-Zytkow object, a bizarre type of hybrid star.

Jun 04, 2014

In a discovery decades in the making, scientists have detected the first of a “theoretical” class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna Żytkow.

Pseudophysics: The New High Priesthood

Wow.  Somewhat in balance to yesterday’s reblog of part one of Coel Hellier’s post defending multiverse theories as scientific, here’s Amir Aczel skewering many of the proponents of multiverses and other untestable cosmological theories.   332 more words
