HAT-P-14b, officially named Sissi also known as WASP-27b,The Exoplanet Handbook By Michael Perryman, p.727 is an extrasolar planet located approximately {{convert|224.2|±|0.6|pc|ly|lk=on}} away in the constellation of Hercules, orbiting the 10th magnitude F-type main-sequence star HAT-P-14. This planet was discovered in 2010 by the HATNet Project using the transit method. It was independently detected by the SuperWASP project.

Host star

The host star is a main-sequence star with the spectral classification F5V and apparent magnitude 9.98, well below the naked-eye visibility limit. It has a mass of {{val|1.386|0.045|ul=M_solar}}, a radius of {{val|1.468|0.054|ul=R_solar}}, and a surface temperature of {{val|6477|13|15|u=K}}. The star HAT-P-14 is named Franz.{{SIMBAD link|HAT-P-14|HAT-P-14}}{{cite web |title=The Extrasolar Planet Encyclopaedia — HAT-P-14 b |url=https://exoplanet.eu/catalog/hat_p_14_b--650/ |work=Extrasolar Planets Encyclopaedia |date=1995 }}

History

The planet HAT-P-14b was named Sissi. The name was selected by Austria as part of the NameExoWorlds campaign for the 100th anniversary of the IAU. The planet was named after the character Sissi in the movie Sissi, who is married to Franz. The role is played by the actress Romy Schneider. The star HAT-P-14 is named Franz.{{Cite web|url=https://www.iau.org/news/pressreleases/detail/iau1912/|title=International Astronomical Union {{!}} IAU|website=www.iau.org|access-date=2020-01-02}}{{Cite web|url=http://www.nameexoworlds.iau.org/final-results|title=Approved names|website=NameExoworlds|language=en|access-date=2020-01-02}}

HAT-P-14b was selected as the target object for testing the James Webb Space Telescope instruments intended for spectroscopic studies of transiting exoplanets. It was chosen because its high surface gravity should produce a very flat spectrum, regardless of the planet's composition.{{cite journal |last1=Rigby |first1=Jane |last2=Perrin |first2=Marshall |last3=McElwain |first3=Michael |last4=Kimble |first4=Randy |last5=Friedman |first5=Scott |last6=Lallo |first6=Matt |last7=Doyon |first7=René |last8=Feinberg |first8=Lee |last9=Ferruit |first9=Pierre |last10=Glasse |first10=Alistair |last11=Rieke |first11=Marcia |display-authors=etal |title=The Science Performance of JWST as Characterized in Commissioning |journal=Publications of the Astronomical Society of the Pacific |year=2023 |volume=135 |issue=1046 |page=048001 |doi=10.1088/1538-3873/acb293 |arxiv=2207.05632|bibcode=2023PASP..135d8001R |s2cid=253735464 }}

Orbit

HAT-P-14b is located very close orbit to its star, taking only 4.6 days to complete one orbit. Observations of the Rossiter–McLaughlin effect with the Keck telescope show that it orbits in a retrograde fashion relative to the rotation axes of its parent star, spin-orbit angle equal to -170.9{{±|5.1}}°.{{citation|arxiv=1206.6105|title=Obliquities of Hot Jupiter Host Stars: Evidence for Tidal Interactions and Primordial Misalignments|year=2012|doi=10.1088/0004-637X/757/1/18 |last1=Albrecht |first1=Simon |last2=Winn |first2=Joshua N. |last3=Johnson |first3=John A. |last4=Howard |first4=Andrew W. |last5=Marcy |first5=Geoffrey W. |last6=Butler |first6=R.
