The designed scheme is proved to be fully well-balanced since it is able to exactly preserve all moving equilibrium solutions, as well as the corresponding steady solutions at rest obtained when the velocity vanishes. Moreover, the proposed scheme is entropy-stable since it satisfies all fully discrete entropy inequalities. In addition, in order to satisfy the required admissibility of the approximate solutions, the positivity of both approximate density and pressure is established. Several numerical experiments attest the relevance of the developed numerical method. An extension to two-dimensional problems is given, applying the one-dimensional framework direction by direction on Cartesian grids.<\/p>","DOI":"10.1090\/mcom\/4088","type":"journal-article","created":{"date-parts":[[2025,4,17]],"date-time":"2025-04-17T09:16:26Z","timestamp":1744881386000},"page":"1251-1292","source":"Crossref","is-referenced-by-count":2,"title":["Towards a fully well-balanced and entropy-stable scheme for the Euler equations with gravity: preserving isentropic steady solutions"],"prefix":"10.1090","volume":"95","author":[{"given":"Christophe","family":"Berthon","sequence":"first","affiliation":[]},{"given":"Victor","family":"Michel-Dansac","sequence":"additional","affiliation":[]},{"given":"Andrea","family":"Thomann","sequence":"additional","affiliation":[]}],"member":"14","published-online":{"date-parts":[[2025,4,17]]},"reference":[{"issue":"6","key":"1","doi-asserted-by":"publisher","first-page":"2050","DOI":"10.1137\/S1064827503431090","article-title":"A fast and stable well-balanced scheme with hydrostatic reconstruction for shallow water flows","volume":"25","author":"Audusse, Emmanuel","year":"2004","journal-title":"SIAM J.
