Gemini Confirms a Free-Floating Planet

Our observed spectrum of PSO J318.5−22 (black) compared to the forward model with our best fit parameters (red). The median residual of the fit is 0.079 (in normalized Fλ units), which is larger than the median uncertainty (0.048) of our observed spectrum. The rms of the residuals (0.12) indicates systematic uncertainties of ≈10%.

PWFS2 (non-siderial targets)

The PWFS2 is available for observing non-siderial targets or when a suitable OIWFS star is not available. There are a few drawbacks with using the P2WFS instead of the OIWFS which are:

 

  • The flexure between the probe arm and the detector has not been quantified

February Call for Proposals

Gemini North and South are accepting proposals for the Fast Turnaround (FT) program. Here, we give information specific to this proposal cycle. Please see the other FT pages - particularly the rules - for general information about the program. Users should be aware that FT-specific proposal templates must now be used for all FT proposals; see the "PIT information" section below.

 

Supermassive Black Hole - That Wasn't
