Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Combining a Diffraction-Limited Coronagraph with Fiber Nulling: A Demonstration of Serially Coupling Different Nullers
Satoshi Itoh, Taro Matsuo, Reiki Kojima +3
We present experimental results of an efficient small-IWA (1 ) high contrast imaging approach realized by co-optimizing a coronagraph front-end with a fiber nulling 2nd…
Japan's Possible Contributions for Coronagraph of the Habitable Worlds Observatory (HWO)
Keigo Enya, Kenta Yoneta, Naoshi Murakami +20
In this paper, we describe Japan's possible contributions for coronagraph of the Habitable Worlds Observatory (HWO) based on our independent study. We are considering to contribute…
Experimental Validation for Serial Conjunction of Diffraction-limited Coronagraph and Fiber Nuller
Satoshi Itoh, Taro Matsuo, Reiki Kojima +2
We report the experimental results of a serially conjoined nuller system, which combines a type of Lyot coronagraph with a fiber nuller. The utilized one-dimensional diffraction-li…
Point Spread Function of Hexagonally Segmented Telescopes by New Symmetrical Formulation
Satoshi Itoh, Taro Matsuo, Shibai Hiroshi +1
A point spread function of hexagonally segmented telescopes is derived by a new symmetrical formulation. By introducing three variables on a pupil plane, the Fourier transform of p…
