HD 209458 planetary transits from Hipparcos photometry

, 2000
During its 39-month mission, Hipparcos observed the star HD 209458 on 89 occasions. Five of these observations are shown to correspond to epochs of planetary transits, with a 2.3±0.4% mean decrease of flux in the Hpband being observed during the transits.

Constraining the oblateness of transiting planets with photometry and spectroscopy [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Rapid planetary rotation can cause the equilibrium shape of a planet to be oblate. While planetary oblateness has mostly been probed by examining the subtle ingress and egress features in photometric transit light curves, we investigate the effect of oblateness on the spectroscopic Rossiter–McLaughlin (RM) signals. We found that

Exoplanet transit spectro-photometry with SOFIA [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractWe present the prospects of observing extrasolar planets with the Stratospheric Observatory for Infrared Astronomy (SOFIA). Our analysis shows that optical and near-infrared photometric and spectrophotometric follow-up observations during planetary transits and\break eclipses will be feasible with SOFIA's instrumentation, especially with the ...

The effects of star spots on transit photometry [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractWe have undertaken an observational program to photometrically monitor several transiting planet host stars. The Rabus et al. result for TrES-1 showed the dramatic effects star spots can have on transit photometry. We will investigate the effects of spots on transit light curves and estimates of planetary radii.

No Conclusive Evidence for Transits of Proxima b in MOST Photometry [PDF]

The Astronomical Journal, 2017
Abstract The analysis of Proxima Centauri’s radial velocities recently led Anglada-Escudé et al. to claim the presence of a low-mass planet orbiting the Sun’s nearest star once every 11.2 days. Although the a priori probability that Proxima b transits its parent star is just 1.5%, the potential impact of such a discovery would be ...

Optical photometry of two transitional millisecond pulsars in the radio pulsar state [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT We present ULTRACAM multiband optical photometry of two transitional millisecond pulsars (tMSPs), PSR J1023+0038 and PSR J1227−4853, taken while both were in their radio pulsar states. The light curves show significant asymmetry about the flux maxima in all observed bands, suggesting an asymmetric source of heating in the system.

Photometry of exoplanetary transits at Osservatorio Polifunzionale del Chianti [PDF]

Experimental Astronomy, 2020
AbstractIn this paper we report the observations of HD189733b, Kepler-41b, Kepler-42b, GJ 436b, WASP-77ab, HAT-P-32b and EPIC 211818569 as measured at the Osservatorio Polifunzionale del Chianti, a new astro-nomical site in Italy. Commissioning observing runs have been done in order to test capabilities, systematics and limits of the system and to ...
