Resumen:
The evolution of young stars and disks is driven by the interplay of
several processes, notably the accretion and ejection of material. These
processes, critical to correctly describe the conditions of planet
formation, are best probed spectroscopically. Between 2020 and 2022,
about 500orbits of the Hubble Space Telescope (HST) are being devoted in
to the ULLYSES public survey of about 70 low-mass (M-star <= 2 M-circle
dot) young (age < 10 Myr) stars at UV wavelengths. Here, we present the
PENELLOPE Large Program carried out with the ESO Very Large Telescope
(VLT) with the aim of acquiring, contemporaneously to the HST, optical
ESPRESSO/UVES high-resolution spectra for the purpose of investigating
the kinematics of the emitting gas, along with UV-to-NIR X-shooter
medium-resolution flux-calibrated spectra to provide the fundamental
parameters that HST data alone cannot provide, such as extinction and
stellar properties. The data obtained by PENELLOPE have no proprietary
time and the fully reduced spectra are being made available to the whole
community. Here, we describe the data and the first scientific analysis
of the accretion properties for the sample of 13 targets located in the
Orion OB1 association and in the -Orionis cluster, observed in
November-December 2020. We find that the accretion rates are in line
with those observed previously in similarly young star-forming regions,
with a variability on a timescale of days (less than or similar to 3).
The comparison of the fits to the continuum excess emission obtained
with a slab model on the X-shooter spectra and the HST/STIS spectra
shows a shortcoming in the X-shooter estimates of less than or similar
to 10%, which is well within the assumed uncertainty. Its origin can be
either due to an erroneous UV extinction curve or to the simplicity of
the modeling and, thus, this question will form the basis of the
investigation undertaken over the course of the PENELLOPE program. The
combined ULLYSES and PENELLOPE data will be key in attaining a better
understanding of the accretion and ejection mechanisms in young stars.
