Internal Structure, Not Environment, Shapes Metallicity Gradients in Low-Mass Galaxies from MaNGA
Anuroop Dasgupta, Namrata Roy, Saumyadip Samui +2
Dwarf and low-mass galaxies are highly sensitive to stellar feedback and gas flows, yet their spatially resolved gas-phase metallicity remains poorly characterised. We measure radi…
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…
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…
The Ophiuchus DIsc Survey Employing ALMA (ODISEA). Substructures as a function of SED Class and disc mass in 100 systems
Trisha Bhowmik, Lucas Cieza, J. M. Miley +17
Current high-resolution studies of protoplanetary discs are biased toward small samples of the brightest (flux > 50 mJy at 225 GHz) and largest systems. We present a complete flux-…
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…
VLT/ERIS observations of the V960 Mon system: a dust-embedded substellar object formed by gravitational instability?
Anuroop Dasgupta, Alice Zurlo, Philipp Weber +8
V960~Mon is an FU Orionis object that shows strong evidence of a gravitationally unstable spiral arm that is fragmenting into several dust clumps. We report the discovery of a new…
The Ophiuchus DIsk Survey Employing ALMA (ODISEA): A Unified Evolutionary Sequence of Planet-Driven Substructures Explaining the Diversity of Disk Morphologies
Santiago Orcajo, Lucas A. Cieza, Octavio Guilera +21
Understanding the origin of substructures in protoplanetary disks and their connection to planet formation is currently one of the main challenges in astrophysics. While some disks…
The Ophiuchus DIsk Survey Employing ALMA (ODISEA): Complete Size Distributions for the 100 Brightest Disks Across Multiplicity and SED Classes
Anuroop Dasgupta, Lucas A. Cieza, Camilo I. Gonzalez Ruilova +16
The size of a protoplanetary disk is a fundamental property, yet most remain unresolved, even in nearby star-forming regions (d 140-200 pc). We present the complete continuu…
