Diffuse ionized gas in galaxies across the Hubble sequence at the CALIFA resolution
E. A. D. Lacerda, R. Cid Fernandes, G. S. Couto +7
We use spatially resolved spectroscopy from the Calar Alto Legacy Field Area (CALIFA) survey to study the nature of the line emitting gas in galaxies of different Hubble types, foc…
Tensile Strength of 67P/Churyumov-Gerasimenko Nucleus Material from Overhangs
N. Attree, O. Groussin, L. Jorda +52
We directly measure twenty overhanging cliffs on the surface of comet 67P/Churyumov-Gerasimenko extracted from the latest shape model and estimate the minimum tensile strengths nee…
The CARMENES search for exoplanets around M dwarfs - HD 147379b: A nearby Neptune in the temperate zone of an early-M dwarf
A. Reiners, I. Ribas, M. Zechmeister +169
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379…
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…
Transport of internetwork magnetic flux elements in the solar photosphere
Piyush Agrawal, Mark P. Rast, Milan Gosic +2
The motions of small-scale magnetic flux elements in the solar photosphere can provide some measure of the Lagrangian properties of the convective flow. Measurements of these motio…
The EDGE-CALIFA survey: the influence of galactic rotation on the molecular depletion time across the Hubble sequence
D. Colombo, V. Kalinova, D. Utomo +15
We present a kpc-scale analysis of the relationship between the molecular depletion time () and the orbital time () across the field of…
