cds-question@unistra.frexoplanetseffective-temperaturemultiple-starsinfrared-photometryastronomical-modelsAriel has been selected as ESA's M4 mission for launch in 2028 and is designed for the characterization of a large and diverse population of exoplanetary atmospheres to provide insights into planetary formation and evolution within our Galaxy. Here we present a study of Ariel's capability to observe currently known exoplanets and predicted Transiting Exoplanet Survey Satellite (TESS) discoveries. We use the Ariel radiometric model (ArielRad) to simulate the instrument performance and find that ~2000 of these planets have atmospheric signals which could be characterized by Ariel. This list of potential planets contains a diverse range of planetary and stellar parameters. From these we select an example mission reference sample (MRS), comprised of 1000 diverse planets to be completed within the primary mission life, which is consistent with previous studies. We also explore the mission capability to perform an in-depth survey into the atmospheres of smaller planets, which may be enriched or secondary. Earth-sized planets and super-Earths with atmospheres heavier than H/He will be more challenging to observe spectroscopically. However, by studying the time required to observe ~110 Earth-sized/super-Earths, we find that Ariel could have substantial capability for providing in-depth observations of smaller planets. Trade-offs between the number and type of planets observed will form a key part of the selection process and this list of planets will continually evolve with new exoplanet discoveries replacing predicted detections. The Ariel target list will be constantly updated and the MRS re-selected to ensure maximum diversity in the population of planets studied during the primary mission life.2019AJ....157..242Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/157/242CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/809/77 : Transiting Exoplanet Survey Satellite (TESS) (Sullivan+, 2015)J/AJ/156/102 : The TESS Input Catalog and Candidate Target ListJ/ApJS/239/2 : Simulated exoplanets from TESS list of targetshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/157/242https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/157/242http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/157/242https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/157/242https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/157/242http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/157/242GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/157/242/table6 (Currently known exoplanets which are considered here to be potential targets for Ariel)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/157/242/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/157/242/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/157/242/table6?GETtext/xml+votable180.050000true133.149213928.33082140.005555555555555556Cone search capability for table J/AJ/157/242/table7 (Planets in the NASA Exoplanet Archive that have been detected by TESS, all of which are found to be suitable for study with Ariel)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/157/242/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/157/242/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/157/242/table7?GETtext/xml+votable180.050000true51.7467619-63.49910060.0055555555555555566/437 790 876 913 1032 1036 1066 1275 1292 2250 2297 2308 2532 2551 2584 2596 2711 2715 2740 2953 3344 3876 4145 4241 4268 4272 4521 4624 4651 4704 4720 4730 4990 5009 5170 5475 5730 6017 6058 6181 6349 6381 6539 6638 7036 7208 7240 7502 7917 8197 8237 8825 9173 9355 9459 9482 9524 9653 10118 10407 10654 10701 10730 10953 11279 11455 12342 12424 12486 12644 12853 12862 12983 13044 13143 13250 13439 13569 13680 13702 13941 14278 14579 14583 14735 14757 14763 14772 14774 14825 14826 14886 14914 14931 14935 14936 14963 14971 14993 15029 15129 15143 15145 15159 15160 15162 15169 15200 15218 15550 15950 16405 16432 16512 16633 16768 16847 16947 17162 17172 17226 17227 17344 17753 17819 17851 17865 18093 18147 18208 18223 18452 18510 18569 18696 18726 18766 18785 18786 18880 18943 19371 20116 20339 20382 20453 20476 20565 20648 20682 20741 20780 20790 20872 21026 21079 21176 21254 21876 22001 22168 22396 22505 22519 22816 22963 23531 24039 24057 24115 24122 24205 24409 24428 24752 24815 24858 24981 25132 25153 25194 25283 25427 25433 25454 25604 25721 25723 25725 25783 25794 25885 25950 26019 26062 26278 26727 26771 26844 26918 26977 26992 27056 27393 27488 27548 27780 27787 28400 28433 28548 29002 29012 29017 29022 29349 29683 30009 30013 30157 30293 30295 30344 30436 30444 30450 30466 30485 30734 31216 31541 31641 31858 32217 32564 32640 32659 32727 32748 32749 32848 33157 33200 33210 33212 33220 33449 33719 33723 33798 34370 34471 34526 34566 34708 34751 34812 34847 34860 34898 34957 35210 35456 35993 36142 36165 36196 36497 36667 36794 38233 38452 38464 38682 39007 39474 39487 39512 39542 39611 39673 39829 39851 40014 40022 40194 40320 40862 42001 42865 42936 42981 42986 42989 43248 43336 43432 43541 43586 43623 43625 43656 43733 43775 43847 43865 43960 44200 44335 44378 44431 44648 44672 44685 45051 45372 45766 45855 45890 45922 46058 46121 46135 46316 46421 46429 46437 46771 47000 47167 47186 47476 47681 48005 48076 48098 48111 48117 48121 48165 48178 48251 48327 48338 48358 48501 48727 48747 48803 48945 49103https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/157/242?format=asciiInfrareddefaultJ/AJ/157/242/table6Currently known exoplanets which are considered here to be potential targets for ArielSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
