HD 80606 b

HD 80606 b is a transiting hot Jupiter orbiting a G-type star (0.98 solar masses) in a 111-day orbit. It was discovered by the radial velocity method in 2001 and a transit was identified in 2011. Its orbit has a high eccentricity, 0.9336, varying from 0.03 to 0.88 AU. Due to the two types of observation and its high eccentricity, it is of interest for further study, e.g., determining characteristics of its atmosphere using its light curve. Characteristics:

• Host star: HD 80606
• Discovery: by the radial velocity method in 2001.
• 217 ly - distance.
• 0.4565 AU - orbital radius (semi-major axis).
• 111 days - orbital period.
• 1 - radius in Jupiter radii.
• 4.1 - Jupiter masses.
• 1500 K - temperature when closest to the host star.
