Absence of extended atmospheres in low-mass star radius-gap planets GJ 9827 b, GJ 9827 d and TOI-1235 b
Vigneshwaran Krishnamurthy, Teruyuki Hirano, Eric Gaidos +20
\textit{Kepler} showed a paucity of planets with radii of 1.5 - 2 around solar mass stars but this radius-gap has not been well studied for low-mass star plane…
Non-detection of Helium in the upper atmospheres of TRAPPIST-1b, e and f
Vigneshwaran Krishnamurthy, Teruyuki Hirano, Guðmundur Stefánsson +37
We obtained high-resolution spectra of the ultra-cool M-dwarf TRAPPIST-1 during the transit of its planet `b' using two high dispersion near-infrared spectrographs, IRD instrument…
First on-sky demonstration of spatial Linear Dark Field Control with the vector-Apodizing Phase Plate at Subaru/SCExAO
S. P. Bos, K. L. Miller, J. Lozi +9
One of the key noise sources that currently limits high-contrast imaging observations for exoplanet detection is quasi-static speckles. Quasi-static speckles originate from slowly…
Overview of focal plane wavefront sensors to correct for the Low Wind Effect on SUBARU/SCExAO
Sebastien Vievard, Steven Bos, Frederic Cassaing +15
The Low Wind Effect (LWE) refers to a phenomenon that occurs when the wind speed inside a telescope dome drops below m/s creating a temperature gradient near the telescope spide…
Large amplitude tip/tilt estimation by geometric diversity for multiple-aperture telescopes
S. Vievard, F. Cassaing, L. M. Mugnier
A novel method nicknamed ELASTIC is proposed for the alignment of multiple-aperture telescopes, in particular segmented telescopes. It only needs the acquisition of two diversity i…
