Spitzer Microlensing Program as a Probe for Globular Cluster Planets. Analysis of OGLE-2015-BLG-0448
Radosław Poleski, Wei Zhu, Grant W. Christie +83
The microlensing event OGLE-2015-BLG-0448 was observed by Spitzer and lay within the tidal radius of the globular cluster NGC 6558. The event had moderate magnification and was int…
Mass Measurements of Isolated Objects from Space-based Microlensing
Wei Zhu, S. Calchi Novati, A. Gould +78
We report on the mass and distance measurements of two single-lens events from the 2015 \emph{Spitzer} microlensing campaign. With both finite-source effect and microlens parallax…
Study of FK Comae Berenices: VII. Correlating photospheric and chromospheric activity
K. Vida, H. Korhonen, I. V. Ilyin +3
We study the connection between the chromospheric and photospheric behaviour of the active late-type star FK Comae. We use spot temperature modelling, light curve inversion based o…
