- Photoionization model for G29.96-0.02 D. Schaerer J.-P. Baluteau P. Cox N. L. Martín Hernández E. Peeters P. Roelfsema C. Morisset Física, Astronomía y Matemáticas 02 96{0 H II REGIONS IRAS18434{0242) ISM: INDIVIDUAL (G29 We present a detailed photoionization model of the Ultra Compact H II (UCH II) region G29.96{0.02 basedon the combined ISO SWS and LWS spectrum. Most of the observed line intensities are reproduced whenG29.96{0.02 is described by a nebula with two di erent density regimes. We nd that the ionizing star iscooler than the spectral type determined from near-IR measurements and that its age is 3 10 6 yr, i.e.,older than the expected lifetime of UCH II regions. Accurate abundances for the main elements are derived. 2002 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57112012 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.12
