Addition to Extrasolar Planets For Extrasolar
planets you can use to get , the semi major
axis. To find the mass of the planet, use the
following formula.

The mass for 16 Cygni did not workout for Clevis
or I. The curve was not a sine curve, and I
wonder if the fact that there is a second star is
possibly causing a three body problem, rather
than 2 body. This has taken me the better part of
two days to go through all the information. The
value of the parent star varied in data from .99
up to 1.1 solar masses, and from a G3 to G5
star. Lets find the mass of 16 Cygni . From last
time Use to find
P the period from the graph is 2.18737303
years so a turned out to be 1.6844 au this
answer was good. To find the mass, use .
a
M is mass, P is the period in years, and v is the
radial velocity in m/sec.

To get v , notice the majority of the peaks are
at about 50m/sec on the left vertical side, and
they go down to about 50 on the bottom.

The best I can do here is estimate both are about
50 , so 5050100 and 100/2 50 so use 50 for v.
Some graphs are better to read then this one was.
Now Im ready
To change to Jupiter mass multiply by1047.45

Most accepted Answer is 1.7 not bad.
I also worked this problem for 51 Persi and got a
to be .056459, good answer, and Mplanet to be .54
Mjupiter . The real answer was .45 Mjupiter. I
found the curve for this one, and I used 68m/sec
for v, but I could have estimated better. The
peaks and the low points are not the same. Ignore
the negative sign, add the numbers together , and
divide by 2. That will be v. Jim Honeycutt
