Title: | Spectro astrometry of the Hα emission of T Cha | Authors: | Cahill, E. Whelan, E. T. Huélamo, N. ALCALA', JUAN MANUEL Rouzé, B. |
Issue Date: | 2017 | Journal: | MEMORIE DELLA SOCIETA ASTRONOMICA ITALIANA | Number: | 88 | First Page: | 771 | Abstract: | For this project we present a spectro-astrometric study of the Hα emission from T Cha, a young stellar object with a transitional disk. The aim is to explore the possibility of detecting a substellar companion using spectro-astrometry. While no spectro-astrometric signal was found in the Hα line it is planned that the next step will be to combine the spectro-astrometric results with estimates of the mass accretion rate for T Cha to put an upper limit on the mass accretion rate onto any companion. | URI: | http://hdl.handle.net/20.500.12386/26719 | URL: | http://sait.oat.ts.astro.it/MSAIt880417/index.html | ISSN: | 0037-8720 | Bibcode ADS: | 2017MmSAI..88..771C | Fulltext: | open |
