FYI
Paris obs. provides online an interesting database of exoplanets completed
with an interactive Java applet
Sure that such catalogs are not rare, even amateur made some, but this Java
applet uses renderings and is particulary fine, completed with all useful
information, however only in Fr or It (why not in English ?!), but graphs
and numbers are universal, aren't they ;-).
http://media4.obspm.fr/exoplanetes/base/index.php
NB. It is even more complete (9 more systems) than the NASA catalog that is
still ignoring e.g. the system PSR B1620-26

Perhaps because US and British sites rarely provide their info in French? :-)

54 Piscium is the southwestern star of the pair 54-55.
upsion Andromedae in 1999 was found to have two more planets, the
first other star with a true 'solar system'. It is sometimes misnamed
as epsilon, an altogether other star.
109 Piscium is sometimes misnamed as 106, which is nu, a wrong
star. 109 sits about one degree at 8:30 o'clock from 107 and is
easiest approached from downtown Aries.
79 Ceti is not labeled in many charts. It is about 1/2 degree
west of 81, between Mira and Caput Ceti.
epsilon Eridani was, with tau Ceti, the first star to be examined
in the 1960s for extraterrestrial intelligence. The second planet is
uncertain, with a period of 102,770 days, about 280 years. The value
in the table is an overflow. This planet is the farthest of the
xtrasolar planets in this table, 40 AU from its star. The inner
planet rounds its periastron during 2007, when it may reflect enough
starlight for an optical image to be captured. if successful, this
will be the first extrasolar planet ever 'seen'.
pi Mensae has the heaviest of the known extrasolar planets in this
table, 10.35 Jupiter masses.
bet Gem is Pollux, marking the head of the sothern Twin. It is the
brightest of planetary stars, surpassing gamma Cephei. The planet runs
in a nearly circular orbit, e = 0.02, It was suspected since 1993 but
confirmed in July 2006.
rho1 Cancri is 55 Cancri. The Bayer letters are a bit inconsistent
among authors in this part of Cancer. Look for the pair made of 53 and
55. rho1 (55) is the northeastern one of this pair. The planet found
in 2004 has semimajor axis of 0.038 AU, or 5.68 million kilometers;
the table value is rounded.
47 Ursae passes virtually exactly thru the zenith of New York.
'lala' Ursae Majoris is laLande 21185, among the fastest and
closest of stars. It is 8.3 lightyears away and scoots thru 4.8 arcsec
southward each year. Its two planets are not yet verified; the
semimajor axes are still unknown. The period of the second planet is
some 30 years; the value in the table is an overflow. To find this
star you need detailed charts to at least 8th magnitude and a small
scope. Other names for this star are GSC2521-2270, HD95735, PPM75640,
SAO62377, BD+36-2147.
14 Herculis is not labeled in many charts. It is the star about
one degree at 7 o'clock from phi Herculis, with 12 at north. Its
second planet, reported in 2005, is still unconfirmed.
mu Arae has the smallest planet yet found. Altho hardly Earthlike
in character, it is only 14 times Earth's mass.
16 Cygni is occasionally mixed up with 61 Cygni, the first star
whose remoteness was certainly measured. 16 is near theta, the western
wing of the swan. 61 is near sigma & tau in the eastern wing.
51 Pegasi is the first bright star, with a Bayer or Flamsteed
designation, found with a planet. Planetary stars before 51 Pegasi
were all beyond easy reach of binoculars.
gamma Cephei is the second brightest planetary star so far
confirmed.

From these, and a couple other, sites I keep a roster of the
brighter planetary stars, those with bayer or Falnsteed number. The
latest revision is only a week old:
ARE THESE STARS LOOKING BACK AT US?
---------------------------------
John Pazmino
NYSkies
nyskiesastronomy@earthlink.net
2006 November 25
With the ongoing discovery of planets around other stars and
increased public awareness of them, I collect here a list of the more
showy of these planetary stars. I include the entire celestial sphere,
recognizing the global residences and travels of NYSkies members.
Most of the stars hosting planets are faint and unappealing.
However, manyare bright enough to see by eye under a dark sky or in
binoculars from New York. I set out here some facts and figures for
these stars. I limit them to stars with Bayer or Flamsteed names so
you can find them on binocular-level staratlases.
Since winter 2004-2005 no new bright planetary stars were found
and 14 Heerculis added a second planet, as yet unconfirmed. There are
several minor updates to the existing data. I added one more decimal
to the SMA and days columns and decimally aligned them. All of these
data will surely be revised as the stars receive continuing attention.
It is still impossible for home telescopes to discern these
planets. Yet it is interesting to point out the stars themselfs to
your visitors. While these stars look entirely ordinary, they hold the
prospect that in their planets there could be people looking back at
us! NYSkies telescopists at starviewing sessions include these stars
on their roster of targets.
The columns 'star' thru 'ly' give the usual specs for the star
and are essentially fixed data. The HD number comes from the Henry
Draper catalog, a prime source for candidate planetary stars and the
usual way to cite them.
'Sun' is the apparent magnitude of Sun as seen from the star.
This is (Sun app magn) = (star app magn) - (star abs magn) + (Sun abs
magn of +4.8). Many of the brighter planetary stars are solar-class
stars. We from them look about as bright as they from us.
'Mjup' is the planet's mass in Jupiter units. The mass is a lower
limit, (mass)*(sin(orbit inclination)). The planet could be far more
massive. In previous revisions, I previously cited Earth units, but
most reports of extrasolar planets compare masses with Jupiter. Jupiter
is 318 Earth masses.
'SMA' is the semimajor axis of the planet's orbit in AU. This
handles the frequent inquiry about the distance of the planet from its
star compared to Earth's distance from Sun. In general, the planets
run in strongly excentric orbits, not closely circular ones like the
planets of our solar system.
'days' is the planet's year in Earth days.
'year' is the when the planet was announced. This typicly is the
end of a multiyear study of the planet to establish its properties.
Following the table are comments about some of the stars.
