WISE mission

Post by Phill on 27th November 2009, 1:21 pm

WISE (Wide field Infrared Survey Explorer) was designed to identify stars closest to the Sun
and could pick up the glow of the coolest ‘failed’ stars, known as brown
dwarfs. These sub-stellar objects range between 13 to 90 Jupiter masses and
have been observed with ground-based telescopes since 1994. WISE might be able
to track down brown dwarfs in our neighbourhood, even those possibly closer
than the nearest known star Proxima Centauri, which is four light years away.
WISE’s first complete survey of solitary brown dwarfs might explain whether
these failed dim stars might account for orbital anomalies in the extreme outer
solar system or disturb the Oort cloud, a spherical cloud of cometary bodies at
one light year distance around our Sun.
interesting!!!

WISE

Can't wait 'til WISE find some more brown dwarfs and hopefully another Sol planet if it exists.

Interesting to see how many BDs exist in the solar neighborhood. Some estimates say the expected number of L and T stars is roughly equal to M stars. About a 50-50 chance they find a BD closer than Proxima Centauri.

Apparently there are some delays launching WISE, caused by problems with launching a military satellite.

(maybe we should merge in this thread?)

Sounds reasonable. Done.

What can WISE do for exoplanet studies? Detect rogue planemos?

WISE Initial Checkout Progressing Nicely

Post by philw1776 on 26th December 2009, 5:08 pm

WISE is checking out nicely and is about to pop its 'lens cap'. After the initial one month checkout, first pictures will be released about a month later. I'd guess late Feb 2010.

WISE site for news, etc.

WISE first light. Lots of red (cool) objects visible when zoomed in.

I'm guessing a lot of these are the hordes of red dwarfs that populate the galaxy.

That red spot at the centre of that image is a near-Earth asteroid.

WISE has found ~100 new brown dwarfs. Six are claimed to be Y-type, one is 9 Light Years away.

Hmmmm... wonder what the distinction between T and Y actually looks like in terms of spectral features.
