[vsnet-ecl 336] FM Leonis - Another HIP EA

["Sebastian Otero" <varsao@fullzero.com.ar>]

More about Hipparcos eclipsing binaries.

About last night's message about V1154 TAURI, I forgot that there was A
RECENT ECLIPSE OBSERVATION from Kari, so it must have helped Chris with the
new period.  I only used Hipparcos three secondary eclipses observations to
determine the longer period...
SORRY !!!


FM LEONIS

FM Leonis will probably be in eclipse next wednesday (for the Americas)
night.
There is a 35.66094 days periodicity confirmed but it is probably not the
true period, since primary eclipse is rather deep (0.5 magnitudes) and lasts
less than 0.27 days.
So the period is -almost for sure- shorter than 35 days.
Anyway, accurate observations can refine the numbers to make further
analysis.

Look at FM Leonis (not a radio station!! :-)) during the time centered in
April 19.272 and see what happens.

Secondary minima are just 0.15 mag. deep.

FM Leonis is at V= 8.45 at maximum. If you catch a primary eclipse you'll
see it as faint as 9.0.

I have prepared a chart available at:

Cheers,
Sebastian.
