Breaks in thin and thick discs of edge-on galaxies imaged in the Spitzer Survey of Stellar Structure in Galaxies (S4G)
Sébastien Comerón, Bruce G. Elmegreen, Heikki Salo +17
Breaks in the radial luminosity profiles of galaxies have been until now mostly studied averaged over discs. Here we study separately breaks in thin and thick discs in 70 edge-on g…
Exploring the Effects of Stellar Rotation and Wind Clearing: Debris Disks Around F Stars
Trisha Mizusawa, Luisa Rebull, John Stauffer +3
We have conducted a study of debris disks around F stars in order to explore correlations between rotation, stellar winds, and circumstellar disks. We obtained new 24 micron photom…
AT Cnc: A Second Dwarf Nova with a Classical Nova Shell
Michael M. Shara, Trisha Mizusawa, Peter Wehinger +5
We are systematically surveying all known and suspected Z Cam-type dwarf novae for classical nova shells. This survey is motivated by the discovery of the largest known classical n…
A unified picture of breaks and truncations in spiral galaxies from SDSS and S^{4}G imaging
Ignacio Martín-Navarro, Judit Bakos, Ignacio Trujillo +21
The mechanism causing breaks in the radial surface brightness distribution of spiral galaxies is not yet well known. Despite theoretical efforts, there is not a unique explanation…
Hα Kinematics of S4G spiral galaxies-I. NGC 864
Santiago Erroz-Ferrer, Johan H. Knapen, Joan Font +22
We present a study of the kinematics of the isolated spiral galaxy NGC 864, using Hα Fabry-Perot data obtained with the GHαFaS instrument at the William Herschel Telescope in La Pa…
The Inter-Eruption Timescale of Classical Novae from Expansion of the Z Camelopardalis Shell
Michael M. Shara, Trisha Mizusawa, David Zurek +3
The dwarf nova Z Camelopardalis is surrounded by the largest known classical nova shell. This shell demonstrates that at least some dwarf novae must have undergone classical nova e…
Early type galaxies with tidal debris and their scaling relations in the Spitzer Survey of Stellar Structure in Galaxies (S4G)
Taehyun Kim, Kartik Sheth, Joannah L. Hinz +21
Tidal debris around galaxies can yield important clues on their evolution. We have identified tidal debris in 11 early type galaxies (T \leq 0) from a sample of 65 early types draw…
GK Per (Nova Persei 1901): HST Imagery and Spectroscopy of the Ejecta, and First Spectrum of the Jet-Like Feature
Michael M. Shara, David Zurek, Orsola De Marco +3
We have imaged the ejecta of GK Persei (Nova Persei 1901 A.D.) with the Hubble Space Telescope (HST), revealing hundreds of cometary-like structures. One or both ends of the struct…
The S4G perspective on circumstellar dust extinction of AGB stars in M100
Sharon E. Meidt, Eva Schinnerer, Juan-Carlos Munoz-Mateos +19
We examine the effect of circumstellar dust extinction on the near-IR contribution of asymptotic giant branch (AGB) stars in intermediate-age clusters throughout the disk of M100.…
