cds-question@unistra.frsolar-systemasteroidsccd-photometryThe discovery rate of near-Earth asteroids (NEAs) has steadily increased over the past three decades, yet the physical characterization of these objects has not kept pace. In an effort to help address this gap, we combined targeted photometric observations, archival data, and sparse photometric data from the ATLAS survey to extract maximum information about NEAs' rotation rates, spin-axis orientations, and shapes. We selected 17 NEAs with a potential for shape reconstruction and applied the lightcurve inversion method to derive their sidereal rotation periods, spin-axis directions, and convex shape models. We successfully determined unique spin and shape models for seven NEAs: (5189) 1990 UQ, (6569) Ondaatje, (7025) 1993 QA, (8566) 1996 EN, (86450) 2000 CK_33_, the Hayabusa2# flyby target (98943) 2001 CC_21_, and (512245) 2016 AU_8_. For additional four asteroids' (66251) 1999 GJ_2_, (137199) 1999 KX_4_, (276786) 2004 KD_1_, and (495615) 2015 PQ_291_ - we constrained their sidereal periods, spin-axis orientations, and in some cases, their shapes. This study highlights the importance of integrating new photometric data with archival dense lightcurves and sparse observations to improve the physical characterization of NEAs, even when working with suboptimal datasets. We constructed 11 NEA models, contributing to the limited set of a few dozen models derived from space missions, radar observations, and lightcurve inversions.2025A&A...695A.139Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/695/A139CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/astorb : Orbits of Minor Planets (Bowell+, 2014-)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/695/A139https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/695/A139http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/695/A139https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/695/A139https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/695/A139http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/695/A139GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/695/A139/tablea1Observational circumstances of studied asteroidsrecnoRecord number assigned by the VizieR team.
