- WASP-19b es un planeta extrasolar que orbita la estrella de tipo G , en la constelación de Vela.Este planeta tiene al menos el 1,15 veces la masa de Júpiter, aunque su radio es mucho mayor (1,31 veces el de Júpiter y 0,13 veces el del Sol), casi como una estrella de baja masa. WASP-19b destaca por tener el período orbital más corto conocido hasta la fecha: 0,7888399 días, es decir, alrededor de 18,932 horas. (es)
- WASP-19b adalah sebuah planet luar surya yang terletak sekitar 881,99 tahun cahaya dari Bumi. Planet ini ditemukan pada tahun 2009 dengan menggunakan metode transit. WASP-19b memiliki massa sebesar 1,069 massa Jupiter. (in)
- WASP-19 b est une planète extrasolaire, remarquable pour être caractérisée par une des plus courtes périodes orbitales connue en 2013 et cela pour toutes les planètes connues : 0,788 839 9 jours soit environ 18,932 heures. Elle a une masse légèrement supérieure à celle de Jupiter (1,114 masses de Jupiter), mais elle a un rayon beaucoup plus grand (1,31 fois celui de Jupiter, soit 0,13 rayons solaires) ; c'est une taille comparable à celle d'une étoile de faible masse. Elle orbite autour de l'étoile WASP-19 dans la constellation des Voiles, située à 270 ± 2 parsecs soit 882 ± 6 années-lumière. Elle possède actuellement en 2013 la période la plus courte découverte pour un Jupiter chaud, car les planètes ayant des périodes orbitales plus courtes sont de composition rocheuse, métallique ou dégénérée. En 2013, les données recueillies par le télescope ASTEP ont pu mettre en évidence des éclipses secondaires et des phases orbitales, soit une première pour des télescopes d'observations au sol. Cela a été possible en raison de la grande taille de la planète et de son petit demi grand-axe. (fr)
- WASP-19b is an extrasolar planet, notable for possessing one of the shortest orbital periods of any known planetary body: 0.7888399 days or approximately 18.932 hours.It has a mass close to that of Jupiter (1.15 Jupiter masses), but by comparison has a much larger radius (1.31 times that of Jupiter, or 0.13 Solar radii); making it nearly the size of a low-mass star. It orbits the star WASP-19 in the Vela constellation. At the time of discovery it was the shortest period hot Jupiter discovered as planets with shorter orbital periods had a rocky, or metallic composition. A study in 2012, utilizing the Rossiter–McLaughlin effect, determined the planetary orbit is well aligned with the equatorial plane of the star, misalignment equal to -15±11°. In 2013, secondary eclipse and orbital phases were barely observed from the data gathered with ASTEP telescope, making it the first detection of such kind through ground-based observations. This was possible due to the large size of the planet and its small semi-major axis. In 2019 the planet was observed with TESS and the eclipse of the planet was measured. The broad variations caused by the changing aspect of the heated face of the planet were measured. The study deduced that the dayside has a temperature of 2240 ± 40 K (1967 ± 40 °C) and that the planet reflects 16 ± 4 percent of the light that falls on it.The last value is relatively high compared to other planets. Despite the short orbital period, orbital decay of WASP-19b was not detected as of 2019. In August 2022, this planet and its host star were included among 20 systems to be named by the third NameExoWorlds project. (en)
