Chemical Abundances of Planetary Nebulae in the Substructures of M31 -- II. The Extended Sample and A Comparison Study with the Outer-disk Group
Xuan Fang, Ruben Garcia-Benito, Martin A. Guerrero +7
We report deep spectroscopy of ten planetary nebulae (PNe) in the Andromeda Galaxy (M31) using the 10.4m GTC. Our targets reside in different regions of M31, including halo streams…
Disrupted asteroid P/2016 G1. II. Follow-up observations from the Hubble Space Telescope
F. Moreno, J. Licandro, M. Mutchler +3
After the early observations of the disrupted asteroid P/2016 G1 with the 10.4m Gran Telescopio Canarias (GTC), and the modeling of the dust ejecta, we have performed a follow-up o…
The GTC exoplanet transit spectroscopy survey. VII. An optical transmission spectrum of WASP-48b
F. Murgas, E. Pallé, H. Parviainen +5
We obtained long-slit optical spectroscopy of one transit of WASP-48b with the Optical System for Imaging and low-Intermediate-Resolution Integrated Spectroscopy (OSIRIS) spectrogr…
Physical and dynamical properties of the anomalous comet 249P/LINEAR
Julio A. Fernández, Javier Licandro, Fernando Moreno +4
Images and low-resolution spectra of the near-Earth Jupiter family comet (JFC) 249P/LINEAR in the visible range obtained with the instrument OSIRIS in the 10.4m Gran Telescopio Can…
The splitting of double-component active asteroid P/2016 J1 (PANSTARRS)
Fernando Moreno, Francisco Pozuelos, Bojan Novakovic +20
We present deep imaging observations, orbital dynamics, and dust tail model analyses of the double-component asteroid P/2016 J1 (J1-A and J1-B). The observations were acquired at t…
Compositional study of asteroids in the Erigone collisional family using visible spectroscopy at the 10.4 m GTC
David Morate, Julia de León, Mário De Prá +5
Two primitive near Earth asteroids, (101955) Bennu and (162173) Ryugu, will be visited by a spacecraft with the aim of returning samples back to Earth. Since these objects are beli…
