TESS Data for Asteroseismology: Timing verification
Carolina von Essen, Mikkel N. Lund, Rasmus Handberg +11
The Transiting Exoplanet Survey Satellite (TESS) is NASA's latest space telescope dedicated to the discovery of transiting exoplanets around nearby stars. Besides the main goal of…
Indications for transit timing variations in the exo-Neptune HAT-P-26b
C. von Essen, S. Wedemeyer, M. S. Sosa +8
From its discovery, the low density transiting Neptune HAT-P-26b showed a 2.1-sigma detection drift in its spectroscopic data, while photometric data showed a weak curvature in the…
Dual-Beam Optical Linear Polarimetry from Southern Skies. Characterisation of CasPol for high precision polarimetry
M. S. Sosa, C. von Essen, I. Andruchow +2
We present a characterization of CasPol, a dual-beam polarimeter mounted at the 2.15 meter Jorge Sahade Telescope, located at the Complejo Astronómico El Leoncito, Argentina. The t…
Ephemeris refinement of 21 Hot Jupiter exoplanets with high timing uncertainties
M. Mallonn, C. von Essen, E. Herrero +32
Transit events of extrasolar planets offer a wealth of information for planetary characterization. However, for many known targets, the uncertainty of their predicted transit windo…
Impact of seeing and host galaxy into the analysis of photo-polarimetric microvariability in blazars - Case study of the nearby blazars 1ES 1959+650 and HB89 2201+044
Marina Sosa, Carolina von Essen, Ileana Andruchow +1
Blazars, a type of Active Galactic Nuclei, present a particular orientation of their jets close to the line ofsight. Their radiation is thus relativistically beamed, giving rise to…
