Observation and Interpretation of Leonid Impact Flashes on the Moon in 2001
We present observations of lunar Leonid impact flashes recorded in 2001 November from Spain. Four impact flashes were detected on November 18. Another flash was...
Observation and Interpretation of Meteoroid Impact Flashes on the Moon
The first unambiguous detection of meteoroids impacting the night side of the Moon was obtained during the 1999 Leonid storm. Up to eight optical flashes were...
Observation and interpretation of the asymmetric Stokes Q, U, and V line profiles in sunspots
We present a first approach to systematic characterization and interpretation of observed asymmetries of Stokes profiles as a function of spatial position...
Observation and Modeling of Anomalous CN Polarization Profiles Produced by the Molecular Paschen-Back Effect in Sunspots
We report novel spectropolarimetric observations of sunspots carried out with the Tenerife Infrared Polarimeter in a near-IR spectral region around 15410 Å...
Observation and Modeling of the Circular Polarization of the Cr I Magnetic-field-induced Transition at 533.03 nm
We study the circular polarization of the magnetic-field-induced transition (MIT) between the 3d 5( 6 S)4d 7 D 2 and 3d 5( 6 S)4p 7 P 4° states of Cr I at 533...
Observation and modelling of main-sequence star chromospheres - XIX. FIES and FEROS observations of dM1 stars
We present 187 high-resolution spectra for 62 different M1 dwarfs from observations obtained with the FIbre-fed Echelle Spectrograph (FIES) on the Nordic...
Observation of a variable, ZZ Ceti white dwarf: GD154
The ZZ Ceti stars form a class of variable white dwarfs: the hydrogen dominated atmosphere ones, which do pulsate in an instability strip in the effective...
Observation of Charge-Dependent Azimuthal Correlations in p -Pb Collisions and Its Implication for the Search for the Chiral Magnetic Effect
Charge-dependent azimuthal particle correlations with respect to the second-order event plane in p -Pb and PbPb collisions at a nucleon-nucleon center-of-mass...
