Sub-Solar Systems ?
(I've never heard this discussed.)
Could systems form where the center mass is insufficient to start a nuclear reaction? If so any idea how prevalent they might be? Have any such systems ever been observed (by infrared emissions or a pecular spectra)? Might they be part of "dark matter" ? Jim H. |

If you are thinking of a brown dwarf with a planetary system, see Sincell M, Science 2001, 292: 1984-85. Protoplanetary disk has been discovered around brown dwarfs. -- gautam |

Tnx. Ah yes, googling "brown dwarf" yields considerable information.
