For Day 2, I started the “Outside
Session” of science talks not let inside. The outside poster
session, where I put the highlight of my approved poster in my sign:
There are missing planets of iron-rich stars at distances that have
periods of 653 to 923 days. Clear out the trash, and there are no
planets there that are not going around iron-poor stars! Zero! None!
Yes, of course, since there are only less than 100 iron-rich planets
that I am looking at, a few will probably be found, but I show that
the distribution of a double peak separated by this deep gap is
better than one in a thousand confidence of being real. What's “the
trash” I swept under the rug here? Any planet whose star has
another star as a companion, to start with. I am not the only one to
have shown that the planets of binary stars are distributed
differently: I find them more mixed, showing some but not other
patters. I also threw out stars that have too low of gravity, usually
because they're old and getting fat, I mean, their radii are getting
larger. I also restrict the temperature range to stars not too
different from the sun.
I am looking a little at the other
stars, the “trash”, and am already seeing them to be “one
(wo)man's trans is another's treasure.” In 2013 I found an
exception to the newly discovered trend of higher eccentricity among
planets hosted by iron-rich stars.
It was my 2012/2013 discovery of that
“eccentricity-iron” correlation, also found independently (at
close to the same time) by two others (Dawson and Murray-Clay, 2013),
that shifted me to study patterns in planets at all periods. Before
then, I have been primarily paying attention to the populations of
planets closest to the star, following the line of looking at planets
going into stars, or “planet destruction.”
Now, I will go pick up a laminated
version of my poster, to continue my “outside poster session.” Laminated, because a typhoon is coming, and yes I will present my poster in the rain!
Cheer me on, and please share this blog
with as many friends as you can!
Astronomers: If you see me, can we take pictures
together? Thanks to all those who have taken pictures!
