Conference on Mathematical Relativity, Canberra, July 1988

The Canberra convention on Mathematical Relativity was once the spotlight of a unique software on the CMA which ran from June - August 1988. With over forty humans collaborating and 27 talks packed into 3 days, the convention used to be a really stimulating and hard adventure for all involved. This quantity comprises reviews on a number of the talks awarded and a few contributed survey papers, and it's was hoping that it'll supply a great advent to themes of present and destiny curiosity in mathematical relativity.

C. pt In this paper we review the recent results concerning the detection of extra-solar planets, with particular emphasis on the cases where a transit event is measured.

Nevertheless in this case flaring events need to be taken into account. One should also recall t h a t solar-type oscillations are multi-periodic. Consequently, the case where several periodic signals are present in the d a t a must be considered. Exoplanet search programs, like those available with the C O R O T mission, allow t o obtain datasets with a sampled time longer t h a n 3 months. Therefore longer datasets should be considered.
