Discovery of a massive giant planet with extreme density around a sub-giant star TOI-4603
We present the discovery of a transiting massive giant planet around
TOI-4603, a sub-giant F-type star from NASA's Transiting Exoplanet Survey
Satellite (TESS). The newly discovered planet has a radius of
, and an orbital period of
days. Using radial velocity measurements with
the PARAS {and TRES} spectrographs, we determined the planet's mass to be
, resulting in a bulk density of
g . This makes it one of the few massive giant
planets with extreme density and lies in the transition mass region of massive
giant planets and low-mass brown dwarfs, an important addition to the
population of less than five objects in this mass range. The eccentricity of
and an orbital separation of AU from its host
star suggest that the planet is likely undergoing high eccentricity tidal (HET)
migration. We find a fraction of heavy elements of and
metal enrichment of the planet () of .
Detection of such systems will offer us to gain valuable insights into the
governing mechanisms of massive planets and improve our understanding of their
dominant formation and migration mechanisms.Comment: accepted for publication in A&A Letter
Complications in orthognathic surgery: An expeditious appraisal
Orthognathic surgery is a aesthetic as well as functional correction surgery of jaw and face. Since it is an elective procedure it comes with its due benefits and complications. There should be a clear distinction between malpractics and complications. The complications could be foreseen if the cause is detected early and adequate treatment provided. The role of oral and maxillofacial surgeons comes into play with a proper understanding of the types, causes and treatment of complications and should deliver this information to patients who develop these complications
