Abstract:	摘要： As part of our ongoing effort to investigate transit timing variations (TTVs) of known exoplanets, we monitored transits of the four exoplanets HAT-P-18b, HAT-P-19b, HAT-P-27b/WASP-40b and WASP-21b. All of them are suspected to show TTVs due to the known properties of their host systems based on the respective discovery papers. During the past three years 46 transit observations were carried out, mostly using telescopes of the Young Exoplanet Transit Initiative. The analyses are used to refine the systems’ orbital parameters. In all cases we found no hints for significant TTVs, or changes in the system parameters inclination, fractional stellar radius and planet-to-star radius ratio. However, comparing our results with those available in the literature shows that we can confirm the already published values. 出版者： London: Oxford University Press 出版日期： 2015-08-21 出處： Monthly notices of the Royal Astronomical Society, 2015-08, Vol.451 (4), p.4060-4072 資源來源： Alma/SFX Local Collection 版權： 2015 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society 2015 版權： Copyright Oxford University Press, UK Aug 21, 2015 識別號： ISSN: 0035-8711 識別號： ISSN: 1365-8711 識別號： ISSN: 1365-2966 識別號： EISSN: 1365-2966 識別號： DOI: 10.1093/mnras/stv1187
