cds-question@unistra.frmultiple-starseclipsing-binary-starsvisible-astronomyWe have identified more than a hundred close triply eclipsing hierarchical triple star systems from data taken with the space telescope TESS. Many of them have outer periods less than or, close to 100 days, hence, we call them "ultracompact hierarchical triples". These systems are noteworthy in that we can potentially determine their dynamical and astrophysical parameters with a high precision. In the present paper we report the comprehensive study of ten new ultracompact triply eclipsing triple star systems, located in the northern ecliptic hemisphere, taken from this larger sample: TICs 198581208, 265274458, 283846096, 337993842, 351404069, 378270875, 403792414, 403916758, 405789362, 461500036. Most of the data for this study come from TESS observations, but we obtained supplemental ground-based photometric measurements for two of the systems. The eclipse timing variation curves extracted from the TESS and the ground-based follow up data, the photometric lightcurves, and the spectral energy distribution are combined in a complex photodynamical analysis to yield the stellar and orbital parameters of all ten systems. The outer periods are in the range of 46.8-101.4 days. We found third-body forced, rapid apsidal motion in four systems. Moreover, TIC 403916758 was found to be a double twin triple (i.e. both the inner and the outer mass ratios are close to unity). All of the systems are substantially flat, with mutual inclination angles of less than 5 degrees. Finally, we have taken the results for the ten systems in the present paper, and combined them with the system parameters for more than 30 other compact triples that we have reported on in previous work, in order to examine some of the global properties of these systems on a statistical basis.2025A&A...703A.153Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/703/A153CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/703/A153https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/703/A153http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/703/A153https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/703/A153https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/703/A153http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/703/A153GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/703/A153/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/703/A153/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/703/A153/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/703/A153/stars?GETtext/xml+votable180.050000true256.106166746.59263890.0055555555555555566/3692 9661 13062 13958 14382 14808 15644 15758 15831 16350https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/703/A153?format=asciiOpticaldefaultJ/A+A/703/A153/starsList of studied starsrecnoRecord number assigned by the VizieR team.
