In this study, we use the third data release from the stellar spectroscopic GALAH Survey, coupled with astrometric data of eDR3 from the Gaia satellite, and other data from NASA's Exoplanet Archive, to refine our understanding of 279 confirmed and candidate exoplanet host stars and their exoplanets. This homogenously analysed data set comprises 105 confirmed exoplanets, along with 146 K2 candidates, 95 TESS Objects of Interest (TOIs), and 52 Community TOIs (CTOIs). Our analysis significantly shifts several previously (unknown) planet parameters while decreasing the uncertainties for others. Our radius estimates suggest that 35 planet candidates are more likely brown dwarfs or stellar companions due to their new radius values. We are able to refine the radii and masses of WASP-47 e, K2-106 b, and CoRoT-7 b to their most precise values yet to less than 2.3 per cent and 8.5 per cent, respectively. We also use stellar rotational values from GALAH to show that most planet candidates will have mass measurements that will be tough to obtain with current ground-based spectrographs. With GALAH's chemical abundances, we show through chemo-kinematics that there are five planet hosts that are associated with the galaxy's thick disc, including NGTS-4, K2-183, and K2-337. Finally, we show that there is no statistical difference between the chemical properties of hot Neptune and hot rocky exoplanet hosts, with the possibility that short-period rocky worlds might be the remnant cores of hotter, gaseous worlds.2022MNRAS.510.2041Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/510/2041CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/506/150 : The GALAH+ Survey DR3 (Buder+, 2021)IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)IV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)I/345 : Gaia DR2 (Gaia Collaboration, 2018)https://exoplanetarchive.ipac.caltech.edu/ : NEA exoplanets home pagehttps://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=k2pandc : K2 exoplanet candidates cataloguehttps://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=TOI : TESS TOI exoplanet candidates cathttps://exofop.ipac.caltech.edu/tess/view_ctoi.php : CTOI exoplanet candidateshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/510/2041https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/510/2041http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/510/2041https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/510/2041https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/510/2041http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/510/2041GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/510/2041/tablea1 (Our refined stellar parameters for 280 confirmed and candidate exoplanet hosting stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/510/2041/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/510/2041/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/510/2041/tablea1?GETtext/xml+votable180.050000true0.77449-62.469320.0055555555555555566/270 310-311 313 322 340 346 378 397 402 406 437 450 467 1064 4252 4255 4268-4269 4298 4313 4345-4346 4521 4623 4627 4630 4632 4659 4675 4682 4688 4698-4699 4704 4708 4720 4730-4731 4733 4897 16488 17999 18003 18012 18018 18118 18130 18139 18142 18148 18163 18188 18345 18347 18350 18490 18496 18569 18572 18588 20543 21024 21026 21234 22078 22297 22896 24122 24202 24205 24294 24752 25427 25433 25443 25446 25452 25551 25577-25578 25604 25625 25627 25644 25646 25655 25660 25683 25686 25689 25697-25698 25708 25710 25725 25756 26113 26258 26959 26975 26990 26992 27025 27109 27680 27704 27777 28941 28943-28944 28954 28976 28979 28981 29014 29031 29033 29037 29042 29312 29349 30752 32862 32980 33006 33039 33044 33046 33049 33064 33070 33078 33085 33089 33096 33128 33134 33140 33145 33157 33163 33172 33200 33224 33230-33231 33241 33404 33426 33507 33798 33805 33821 33823-33824 33839 33854 33862 33868 33883 33890 33892 33932 34254 34832 34840 34848 34946 37283 37376 37390-37393 37402 37404 37424 37426 37434 37485 37487 37518-37519 37528 37548 37550-37551 37561 37593-37594 37611 37766 38246 38928 38963 38977 38979 39016 39056-39057 39075 39077 40014 40230 40382 40512 40553 40564 40810 40862 41069 42874 42910 42948 42978 42984 43233 43394 43526 43541 43668 43932 44307 44323 44335 44362 44378 44404 44431 44474 44685 44771 45314 45343 45905 45922 45928 45940 47167 47446 47449 47678 48028-48029 48047 48121 48241 48501 48503https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/510/2041?format=asciidefaultJ/MNRAS/510/2041/tablea1Our refined stellar parameters for 280 confirmed and candidate exoplanet hosting starsrecnoRecord number assigned by the VizieR team.
