Tadpole galaxies have a giant star-forming region at the end of an elongated intensity distribution. Here we use Sloan Digital Sky Survey data to determine the...
Tadpole galaxies, with a bright peripheral clump on a faint tail, are morphological types unusual in the nearby universe but very common early on. Low mass...
Long Characteristics versus Short Characteristics in 3D Radiative Transfer Simulations of Polarized Radiation
We compare maps of scattering polarization signals obtained from three-dimensional (3D) radiation transfer calculations in a magnetoconvection model of the...
Long-term Monitoring, Time Delay, and Microlensing in the Gravitational Lens System Q0142-100
We present 12 yr of monitoring of the gravitational lens Q0142-100 from the Teide Observatory. The data, taken from 1999 to 2010, comprise 105 observing nights...
Looking for a Connection between the Am Phenomenon and Hybrid δ Sct -γ Dor Pulsation: Determination of the Fundamental Parameters and Abundances of HD 114839 and BD +18 4914
δ Sct-γ Dor hybrids pulsate simultaneously in p- and g-modes, which carry information on the structure of the envelope as well as to the core. Hence, they are...
Looking for Gravity-Mode Multiplets with the GOLF Experiment aboard SOHO
This paper is focused on the search for low-amplitude solar gravity modes between 150 and 400 μHz, corresponding to low-degree, low-order modes. It presents...
Low-Ionization Structures in Planetary Nebulae: Confronting Models with Observations
Around 50 planetary nebulae (PNs) are presently known to possess ``small-scale'' low-ionization structures (LISs) located inside or outside their main nebular...
Lowly Polarized Light from a Highly Magnetized Jet of GRB 190114C
We report multicolor optical imaging and polarimetry observations of the afterglow of the first TeV-detected gamma-ray burst (GRB), GRB 190114C, using the...
LP 714-37: A Wide Pair of Ultracool Dwarfs Actually Is a Triple
LP 714-37 was identified by Phan-Bao et al. as one of the very few wide pairs of very low mass (VLM) stars known to date, with a separation of 33 AU. Here we...
