X-shooter survey Across Regions and Ages to probe Disk Evolution (ARADE): Accretion properties in Orion A and their relation with disk masses
Lara Piscarreta, Giacomo Beccari, Carlo Manara +10
We present a homogeneous VLT/X-Shooter study of accretion in young stellar objects spanning the entire Orion A complex. Our sample includes 91 pre-main-sequence stars hosting a pro…
Far-ultraviolet flux distribution in Orion and its relation to stellar accretion
Rossella Anania, Andrew J. Winter, Miguel Vioque +8
Orion is the closest region hosting active star formation and young OBA stars. Computing far-ultraviolet (FUV) fluxes at its stars is essential to connect stellar and protoplanetar…
X-Shooter survey of disk accretion in Upper Scorpius II. A lack of correlation between accretion rates and disk properties
A. Empey, C. F. Manara, R. Garcia Lopez +19
The evolution of protoplanetary discs is intertwined with the process of planet formation, growth and migration. Studies of nearby star forming regions of different ages and proper…
The ExoGRAVITY survey: A K-band spectral library of giant exoplanet and brown dwarf companions
J. Kammerer, T. O. Winterhalder, S. Lacour +106
Direct observations of exoplanet and brown dwarf companions with near-infrared interferometry, first enabled by the dual-field mode of VLTI/GRAVITY, provide unique measurements of…
Probing accretion and stellar properties in the Orion Nebula with VLT/X-Shooter
L. Piscarreta, G. Beccari, R. A. B. Claes +6
Multiple photometric studies have reported the presence of seemingly older accreting pre-main sequence stars (PMS) in optical colour-magnitude diagrams (CMDs). We investigate this…
Rapid follow-up observations of infant supernovae with the Gran Telescopio Canarias
Lluís Galbany, Claudia P. Gutiérrez, Lara Piscarreta +21
The first few hours of a supernova (SN) contain significant information about the progenitor system. The most modern wide-field surveys that scan the sky repeatedly every few days…
Spectral characterization of young LT dwarfs
L. Piscarreta, K. Mužić, V. Almendros-Abad +1
We aim to provide a detailed characterization of near-infrared spectra for young LT brown dwarfs, including robust spectral typing, calibrating spectral indices, identifying possib…
The enigmatic double-peaked stripped-envelope SN 2023aew
Tuomas Kangas, Hanindyo Kuncarayakti, Takashi Nagao +29
We present optical and near-infrared photometry and spectroscopy of SN 2023aew and our findings on its remarkable properties. This event, initially resembling a Type IIb supernova…
Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq
Jeniveve Pearson, David J. Sand, Peter Lundqvist +85
We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 ( Mpc),…
SN 2022joj: A Potential Double Detonation with a Thin Helium shell
E. Padilla Gonzalez, D. A. Howell, G. Terreran +34
We present photometric and spectroscopic data for SN 2022joj, a nearby peculiar Type Ia supernova (SN Ia) with a fast decline rate ( mag). SN 2022joj shows exce…
Early Spectroscopy and Dense Circumstellar Medium Interaction in SN 2023ixf
K. Azalee Bostroem, Jeniveve Pearson, Manisha Shrestha +53
We present the optical spectroscopic evolution of SN~2023ixf seen in sub-night cadence spectra from 1.18 to 14 days after explosion. We identify high-ionization emission features,…
Photometric and spectroscopic analysis of the Type II SN 2020jfo with a short plateau
B. Ailawadhi, R. Dastidar, K. Misra +34
We present high-cadence photometric and spectroscopic observations of SN~2020jfo in ultraviolet and optical/near-infrared bands starting from to days after the…
