SIGNALS, the Star formation, Ionized Gas, and Nebular Abundances Legacy Survey, is a large observing programme designed to investigate massive star formation...
Signature of oscillations in coronal bright points
A detailed study of two consecutive bright points observed simultaneously with the Coronal Diagnostic Spectrometer (CDS), the Extreme ultraviolet Imaging...
Signatures of Convection in the Spectrum of Procyon: Fundamental Parameters and Iron Abundance
We have observed the spectrum of Procyon A (F5 IV) from 4559 to 5780 Å with a signal-to-noise ratio of ~103 and a resolving power of 2×105. We have measured the...
Signatures of Incomplete Paschen-Back Splitting in the Polarization Profiles of the He I λ10830 Multiplet
We investigate the formation of polarization profiles induced by a magnetic field in the He I multiplet at 10830 Å. Our analysis considers the Zeeman splitting...
Signatures of Magnetic Activity: On the Relation between Stellar Properties and p-mode Frequency Variations
In the Sun, the properties of acoustic modes are sensitive to changes in the magnetic activity. In particular, mode frequencies are observed to increase with...
Signatures of Magnetic Reconnection at the Footpoints of Fan-shaped Jets on a Light Bridge Driven by Photospheric Convective Motions
Dynamical jets are generally found on light bridges (LBs), which are key to studying sunspot decay. So far, their formation mechanism is not fully understood...
Signatures of sunspot oscillations and the case for chromospheric resonances
Sunspots host a large variety of oscillatory phenomena, whose properties depend on the nature of the wave modes and the magnetic and thermodynamic structure of...
Signatures of the Galactic bar in high-order moments of proper motions measured by Gaia
Our location in the Milky Way provides an exceptional opportunity to gain insight on the galactic evolution processes, and complement the information inferred...
Signatures of the Galactic bar on stellar kinematics unveiled by APOGEE
Bars are common galactic structures in the local universe that play an important role in the secular evolution of galaxies, including the Milky Way. In...
