SETI Talks archive: http://seti.org/talks

Objects with masses (less than 0.08 solar masses) too small to sustain hydrogen fusion were theorized to exist five decades ago, and discovered 30 years later, due to their extreme faintness. Even less massive (less than 13 Jupiter or less than 0.01 solar masses) are the planetary mass objects (PMOs, so-called because they are not orbiting a star.

We have recently discovered large populations of such free-floating PMOs and brown dwarfs in the nearest star-forming regions to Earth, when they are at their brightest and most amenable to detection.

Do such objects outnumber the stars in the Galaxy? Do they have their own planetary or moon systems?

Could these sustain surface or subsurface liquid water for eons via tidal heating and thus provide environments conducive for the development of microbial life?

    This is really interesting stuff… Great hangout

    Another great talk. On a sidenote, is there any news about Kepler? How is
    it third reaction wheel going? I haven’t heard anyhing about it for a
    while…

    very good lecture

    what would happen if one of them were to end up going through our solar
    system?

    Hi single subject! You’re welcome!

  8. Anon Ymous says:

    Great talk! Thank you for all of the preparation that obviously went into
    it. Look forward to more of these in the future.

    …these dwarf stars should also have a radio-frequency…specific to the
    type of dwarf…it should be there…just gotta be able to tune it in….

    Here’s a SETI talk from Mary Barsony on “Free Floating Planetary Mass
    Objects.”

    Barsony is a research scientist at the SETI Institute in California. She’s
    an astrophysicist who has worked on some amazing topics – from
    near-infrared array studies of embedded young star clusters to
    submillimeter telescope studies of late-stage protostars. She’s also served
    as the University of California President’s Fellow in the Astronomy
    Department at U.C. Berkeley, and as a Professor of Physics at U.C.
    Riverside.
