After years of obscurity in the backwaters of astronomy, the recent epochal detections of giant planets around nearby stars has put the search for extrasolar planets on its center stage. The discoveries of 51 Peg B [l], 7 Boo B, 55 Cnc B and C, 70 Vir B, and 47 UMa B [2-41, and the belated recognition that HD114762 [5] is in this class have galvanized the planetary science community, astronomers, and the public at large. Table 1 lists these newly-discovered planets, in order of increasing semi-major axis, along with the giant planets in our solar system and the brown dwarf G1229 B [6]. Also shown are Mpsilz(i), orbit period, eccentricity, distance to the sun, estimated surface temperature, and age (when an age could be comfortably assigned). The wide range in mass (0.5 MJ to N 10 MJ ) and period (3.3 days to N 20 years), as well as the proximity of many of the planets to their primaries, was not anticipated by most planetary scientists. Though the technique of Doppler spectroscopy used to find most of these planets selects for massive, nearby objects, their variety and existence is a challenge *The authors would like to acknowledge the support of NASA via grant NAGW-2817 and of the NSF via grant AST93-18970.

N2 - The recent discoveries of giant planets around nearby stars has galvanized the planetary science community, astronomers, and the public at large. Since direct detection is now feasible, and is suggested by the recent acquisition of G1229 B, it is crucial for the future of extrasolar planet searches that the fluxes, evolution, and physical structure of objects from Saturn's mass to 15 Juipter masses be theoretically investigated. We discuss our first attempts to explore the characteristics of extrasolar giant planets (EGPs), in aid of both NASA's and ESA's recent plans to search for such planets around nearby stars.
