The TP3-WFS: a new guy in town
Carlos Colodro-Conde, Sergio Velasco, Roberto López +11
The TP3-WFS (Two Pupil Plane Positions Wavefront Sensor) is, to the best of the authors' knowledge, the first physical implementation of the geometrical wavefront reconstruction al…
Processing diffraction-limited images through innovative Super-Resolution techniques
E. Quevedo, S. Velasco, C. Colodro-Conde +10
In the ELTs era, where the need for versatile and innovative solutions to produce very high spatial resolution images has become a major issue, the search of synergies with other s…
The adaptive optics lucky imager (AOLI): presentation, commissioning, and AIV innovations
Sergio Velasco, Carlos Colodro-Conde, Roberto L. López +6
Here we present the Adaptive Optics Lucky Imager (AOLI), a state-of-the-art instrument which makes use of two well proved techniques, Lucky Imaging (LI) and Adaptive Optics (AO), t…
ALIOLI: Adaptive and Lucky Imaging Optics Lightweight Instrument
Sergio Velasco, Roberto L. López, Alejandro Oscoz +1
As a consequence of the evolution in the design and of the modularity of its components, AOLI for the William Herschel Telescope (WHT 4.2m) is much smaller and more efficient than…
P-REx: The Piston Reconstruction Experiment for Infrared Interferometry
Felix Widmann, Jörg-Uwe Pott, Sergio Velasco
For sensitive infrared interferometry, it is crucial to control the differential piston evolution between the used telescopes. This is classically done by the use of a fringe track…
Three Small Planets Transiting a Hyades Star
John H. Livingston, Fei Dai, Teruyuki Hirano +33
We present the discovery of three small planets transiting K2-136 (LP 358 348, EPIC 247589423), a late K dwarf in the Hyades. The planets have orbital periods of $7.9757 \pm 0.0011…
Using binary statistics in Taurus-Auriga to distinguish between brown dwarf formation processes
M. Marks, E. L. Martín, V. J. S. Béjar +6
Whether BDs form as stars through gravitational collapse ("star-like") or BDs and some very low-mass stars constitute a separate population which form alongside stars comparable to…
Multi-filter transit observations of HAT-P-3b and TrES-3b with multiple Northern Hemisphere telescopes
Davide Ricci, Pedro Valdés Sada, Samuel Navarro-Meza +17
We present a photometric follow-up of transiting exoplanets HAT-P-3b and TrES-3b, observed by using several optical and near-infrared filters, with four small-class telescopes (D =…
Completing the puzzle: AOLI full-commissioning fresh results and AIV innovations
Sergio Velasco, Carlos Colodro-Conde, Roberto L. López +13
The Adaptive Optics Lucky Imager (AOLI) is a new instrument designed to combine adaptive optics (AO) and lucky imaging (LI) techniques to deliver high spatial resolution in the vis…
Laboratory and telescope demonstration of the TP3-WFS for the adaptive optics segment of AOLI
C. Colodro-Conde, S. Velasco, J. J. F. Valdivia +15
AOLI (Adaptive Optics Lucky Imager) is a state-of-art instrument that combines adaptive optics (AO) and lucky imaging (LI) with the objective of obtaining diffraction limited image…
Commissioning and First Observations with Wide FastCam at the Telescopio Carlos Sánchez
Sergio Velasco, Urtats Etxegarai, Alejandro Oscoz +9
The FastCam instrument platform, jointly developed by the IAC and the UPCT, allows, in real-time, acquisition, selection and storage of images with a resolution that reaches the di…
An instrumental puzzle: the modular integration of AOLI
Roberto L. López, Sergio Velasco, Carlos Colodro-Conde +12
The Adaptive Optics Lucky Imager, AOLI, is an instrument developed to deliver the highest spatial resolution ever obtained in the visible, 20 mas, from ground-based telescopes. In…
AOLI: Near-diffraction limited imaging in the visible on large ground-based telescopes
Craig Mackay, Rafael Rebolo, David King +11
The combination of Lucky Imaging with a low order adaptive optics system was demonstrated very successfully on the Palomar 5m telescope nearly 10 years ago. It is still the only sy…
High spatial resolution optical imaging of the multiple T Tauri system LkHα 262/LkHα 263
S. Velasco, R. Rebolo, A. Oscoz +12
We report high spatial resolution i' band imaging of the multiple T Tauri system LkH 262/LkH 263 obtained during the first commissioning period of the Adaptive Optics Lucky I…
The K2-ESPRINT Project IV: A Hot Jupiter in a Prograde Orbit with a Possible Stellar Companion
Teruyuki Hirano, Grzegorz Nowak, Masayuki Kuzuhara +19
We report on the detection and early characterization of a hot Jupiter in a 3-day orbit around K2-34 (EPIC~212110888), a metal-rich F-type star located in the K2 Cycle 5 field. Our…
