Planetary Habitability Laboratory @ UPR Arecibo - 0 views

  •  
    "The Planetary Habitability Laboratory (PHL) is a research and education laboratory dedicated to studies of the habitability of Earth, the Solar System, and exoplanets. Check the projects link for more details about the scientific projects. There are also links to scientific and educational materials, data and software tools related to planetary science and astrobiology that might be of interest to scientists, students, and the general public. The PHL is managed by the University of Puerto Rico at Arecibo."

The Habitable Exoplanets Catalog - Planetary Habitability Laboratory @ UPR Arecibo - 1 views

  •  
    "The Habitable Exoplanets Catalog (HEC) is an online database of potentially habitable worlds discoveries for scientists, educators, and the general public. The catalog identifies, classifies, and compares exoplanets of interest for the search for life in the universe. There is no guarantee that any of these worlds are habitable since we know very little of them now. The catalog is maintained by the Planetary Habitability Laboratory @ UPR Arecibo and is updated as new data is available."

Why Are Quark Stars So Strange? : Discovery News - 1 views

  • First things first, neutron stars, quark stars and black holes are all born via the same mechanism: a supernova. But each of the three are progressively more massive, so they originate from supernovae produced by progressively more massive stars. So, what if a star exploded, producing something a little too massive to be called a neutron star? Well, neutron stars resist collapsing under their own gravitational pull by a characteristic of matter known as neutron degeneracy. This produces an outward force called neutron degeneracy pressure. What if the neutron star born after a supernova is too massive for this neutron degeneracy pressure to hold up against the neutron star's own gravity? In this case, it's up to the quarks that make up the neutrons to take over, preventing the body from collapsing any further. Single neutrons are composed of three quarks (two "down" quarks and one "up" quark). When quark degeneracy pressure kicks in, a quark star may be produced; the free "up" and "down" quarks get converted into "strange" quarks. Therefore, a quark star (also known as a "strange star") is made up of strange matter.
  • Using what we know from the Standard Model of particle physics, a massive quark star may have enough gravitational energy to start 'burning' strange matter. The quarks inside the core of the quark star may be abused so badly by gravitational pressure that the quarks will be converted into pure energy and neutrinos.
  • The fascinating thing with this scenario is that the quark star matter will be so dense that even the neutrinos cannot escape. However, this release of energy and generation of neutrinos creates an outward pressure countering the relentless inward gravitational pull.

  • Dai calls this extreme strange matter-burning quark star an "electroweak star"
  • Saving the best till last, the electroweak star's core would therefore be as extreme as the universe was only 10-10 seconds (that's 0.0000000001 seconds) after the Big Bang. These extreme objects would be like mini-Big Bang laboratories, maintaining a pressure where the electromagnetic and weak forces are so intertwined, they cannot be distinguished.
