Star
The star is cooler, more luminous, similar mass, and larger than our Sun. This star is 22% older than our Sun and with metallicity nearly doubled with the Sun, based on its abundance of iron.
Planetary system
In 2002, a 2.1 MJ planet HD 73526 b was discovered orbiting its star in an orbit just a little smaller than that of Venus' orbit around the Sun. This planet receives insolation 3.65 times that of Earth or 1.89 times that of Venus. This single planetary system was known for four years until 2006 when 2.3 MJ second planet HD 73526 c was found. This planet forms 2:1 orbital resonance with the planet b. Although those masses are minimal as inclinations of these planets are not known, orbital stability analysis indicated that orbital inclinations of both planets are likely to be near 90°, making minimum masses very close to the true masses of the planets.
