Searching for Embedded Protoplanets with the Keck/NIRC2 Vortex Coronagraph: Confirmation of a Core-accretion Planet in the Narrow Gap of the Elias 2-24 Disk
Andrea Bernardi, Alice Zurlo, Lucas A. Cieza +8
We present high-contrast imaging observations of seven stars obtained with the Keck/NIRC2 vortex coronagraph between 2018 May and June in the and bands. All targets host…
Reduced-Space Multi-Fidelity Bayesian Optimization of Process Simulation Models
Niki Triantafyllou, Andrea Bernardi, Maria M. Papathanasiou
Optimizing industrial process flowsheets is often computationally prohibitive due to the high cost of rigorous simulations and the curse of dimensionality inherent in complex desig…
SaNDi-SHoP: Searching for Satellites'N'Disks with a Star-Hopping Program II. Spectrophotometric analysis and orbital monitoring of directly imaged companions
Andrea Bernardi, Alice Zurlo, Cecilia Lazzoni +6
Over the past decade, advances in high-contrast imaging instrumentation, coupled with extreme adaptive optics systems, have enabled the discovery of tens of planets and brown dwarf…
SaNDi-SHoP: Searching for Satellites'N'Disks with a Star-Hopping Program I. Analysis of the close surroundings of DI companions
Cecilia Lazzoni, Alice Zurlo, Silvano Desidera +6
We aim to search for satellites and circumplanetary or circumsubstellar disks around directly imaged substellar companions, exploring their immediate environment to constrain the c…
