HD 89744 [SEP] constellation
HD 89744
HD 89744 is an F-type subgiant star about 126 light years away in the constellation of Ursa Major. This star has 1.45 times the mass of the Sun, with a projected rotational velocity of 8.0 km s. In 2004, stellar companion HD 89744 B (~0.076 solar mass) with a projected separation of 2,456 AU was detected.
Planetary system.
In April 2000, a planet was discovered using radial velocity measurements taken at Fred Lawrence Whipple Observatory and Lick Observatory. The orbital parameters were updated
HD 89744 b
HD 89744 b is an eccentric Jupiter extrasolar planet orbiting the star HD 89744.
In a simulation of a 10 million year span, this planet swept away all test particles "except for a narrow region near the 8:3 resonance". There can be no planets in this star's habitable zone. Observation has ruled out any planet over 0.7 Jupiter mass within a year period.
