HD 83443 is an orange dwarf star approximately 134 light-years away in the constellation of Vela. As of 2000, at least one extrasolar planet has been confirmed to be orbiting the star. The star HD 83443 is named Kalausi. The name was selected in the NameExoWorlds campaign by Kenya, during the 100th anniversary of the IAU. The word Kalausi means a very strong whirling column of wind in the Dholuo language.
HD 28185 is a yellow dwarf star similar to the Sun located 128 light-years away from Earth in the constellation Eridanus. The designation HD 28185 refers to its entry in the Henry Draper catalogue. The star is known to possess one long-period extrasolar planet.
HD 102195 is an orange-hued star in the zodiac constellation of Virgo with a confirmed exoplanet companion. With an apparent visual magnitude of 8.07, the star is too faint to be seen with the naked eye. The distance to HD 102195 can be estimated from its annual parallax shift of 34.06 mas, yielding a separation of 95.8 light years. It is moving further away from the Earth with a heliocentric radial velocity of 1.85 km/s. This is a high proper motion star and a possible member of the η Cha stellar kinematic group.
HD 192699 is a yellow subgiant star located approximately 214 light-years away in the constellation of Aquila. It has the apparent magnitude of 6.45. Based on its mass of 1.68 solar, it was an A-type star when it was a main-sequence. In April 2007, a planet was announced orbiting the star, together with HD 175541 b and HD 210702 b.
HD 52265 b, formally named Cayahuanca, is a gas giant exoplanet located approximately 98 light-years away in the constellation of Monoceros, orbiting the star HD 52265. The planet has a minimum mass slightly more than that of Jupiter. Mean distance between the planet and the star is half that of Earth from the Sun. It was discovered by both the California and Carnegie Planet Search team and the Geneva Extrasolar Planet Search team independently of each other. By studying the fluctuations of the brightness of a host star, the inclination of the stars equator was determined. This allowed to calculate its true mass, assuming that the planet orbits in the plane of the star's equator.
BD-17°63 b, formally named Finlay, is an extrasolar planet located approximately 112.5 light-years away in the constellation of Cetus, orbiting the 10th magnitude K-type main sequence star BD-17°63. This planet has a minimum mass of 5.1 MJ and orbits at a distance of 1.34 astronomical units from the star. The distance ranges from 0.62 AU to 2.06 AU, corresponding to the eccentricity of 0.54. One revolution takes about 656 days.
BD−17 63 is a low-mass K type star in the southern constellation Cetus. It is a 9th magnitude star at a distance of 113 light years from Earth.
HD 43197 is a star with an exoplanetary companion in the southern constellation of Canis Major. It has been given the proper name Amadioha, as selected by Nigeria during the NameExoWorlds campaign that celebrated the 100th anniversary of the IAU. Amadioha is the god of thunder in Igbo mythology. It has an apparent visual magnitude of 8.98, meaning this is a ninth magnitude star that is too dim to be visible to the naked eye. The system is located at a distance of 204 light-years from the Sun based on parallax measurements, and is drifting further away with a radial velocity of +72 km/s. It made its closest approach some 583,000 years ago when it came to within 87 light-years.
The Magellan Planet Search Program is a ground-based search for extrasolar planets that makes use of the radial velocity method. It began gathering data in December 2002 using the MIKE echelle spectrograph mounted on the 6.5m Magellan II "Clay" telescope located within the Las Campanas Observatory in Chile. In 2010, the program began using the newly commissioned Planet Finder Spectrograph (PFS), an instrument purpose-built for precise radial velocity measurement.
HD 86226 is a G-type yellowish white star found in the constellation of Hydra.
HD 129445 is a G-type star found in the Circinus constellation located 219 light-years away from the Sun based on parallax. It is invisible to the naked eye with an apparent visual magnitude of 8.80. The star was observed by the Magellan Planet Search Program due to its absolute visual magnitude and high metallicity. The Magellan program conducted 17 doppler velocity measurements, which spans a full orbital period. The results led the program to detect a planet dubbed HD 129445 b. In 2023, the inclination and true mass of HD 129445 b were determined via astrometry.
HD 129445 b is an eccentric Jupiter gas giant exoplanet orbiting the star HD 129445 which was discovered by the Magellan Planet Search Program in 2010. Its minimum mass is 1.6 times Jupiter's, and it takes 5 years to complete one orbit around HD 129445, a G-type star approximately 219 light years away. In 2023, the inclination and true mass of HD 129445 b were determined via astrometry.
HD 152079 is a star in the constellation Ara.
HD 152079 b is an eccentric Jupiter gas giant discovered by the Magellan Planet Search Program in 2010.
HD 164604 is a single star in the southern constellation of Sagittarius constellation. It has the proper name Pincoya, as selected in the NameExoWorlds campaign by Chile, during the 100th anniversary of the IAU. Pincoya is a female water spirit from southern Chilean mythology who is said to bring drowned sailors to the Caleuche so that they can live in the afterlife. A 2015 survey ruled out the existence of any additional stellar companions at projected distances from 13 to 340 astronomical units. It is known to host a single super-Jupiter exoplanet.
HD 175167 is a star with an exoplanet companion in the southern constellation of Pavo. It is too faint to be visible with the naked eye at an apparent visual magnitude of 8.01. The system is located at a distance of 232 light years from the Sun based on parallax measurements, and it is drifting further away with a radial velocity of 5 km/s. It shows a high proper motion, traversing the celestial sphere at an angular rate of 0.190 arcsec yr−1.
HD 175167 b is an extra-solar planet orbiting HD 175167, which is a G type star within the Pavo constellation around 219 light years away from the Earth. The planet was discovered by the Magellan Planet Search Program as the astronomical object fit the Keplerian orbital model. During the observations 13 doppler velocity tests were conducted, which showed this object's mass was at least 7.8 Jovian-masses and its orbit has a high eccentricity. The exoplanet takes 3.53 years to complete a full stellar orbit.
HD 86226 b is a gas giant exoplanet discovered by the Magellan Planet Search Program in 2010. It was confirmed in data collected by the CORALIE spectrograph on the Swiss 1.2-metre Leonhard Euler Telescope in 2012. It takes about 4.6 years to orbit its G-type star and was initially believed to have a minimal mass of 0.92 Jupiters. Discovery of the second planet in the system has led to the revised mass of HD 86226 b in 2020, now estimated to be 0.45+0.04
−0.05MJ.
HD 212771 b is an extrasolar planet orbiting the G-type star HD 212771 approximately 364 light years away in the constellation Aquarius.
HD 181342 b is an extrasolar planet orbiting the K-type star HD 181342 approximately 394 light years away in the constellation Sagittarius.
