are in solar units and p is the mean density of the planet, which could be somewhere in the range O.S < p < 8 g cm~3. A minimal detection of the occultation requires that A 3~, where ~ is the photometric fractional uncertainty in the measurements.

84 t = 3 x 10~9~~210° Seconds where ma is the apparent visual magnitude of the star. For main-sequence stars, the apparent magnitude can be reckoned from the mass and distance: me ~ - 8.4 log M*

of 10, this requires r < 13 parsecs and No=34X 103N, =3.4x 104 stars. However, there are only about 1000 stars within 13 parsecs, so this method could not give an accurate estimate of the fraction of even Jupiter-size planets occurring around nearby stars.
