Evidence for Pulsation-Driven Mass Loss from delta Cephei
M. Marengo, N. R. Evans, L. D. Matthews +7
We found the first direct evidence that the Cepheid class namesake, delta Cephei, is currently losing mass. These observations are based on data obtained with the Spitzer Space Tel…
New Evidence for Mass Loss from delta Cephei from HI 21-cm Line Observations
L. D. Matthews, M. Marengo, N. R. Evans +1
Recently published Spitzer observations of the classical Cepheid archetype delta Cephei revealed an extended dusty nebula surrounding this star and its hot companion. The infrared…
Synthetic Cepheid Period-Luminosity & Period-Color Relations in Spitzer's IRAC Bands
C. -C. Ngeow, M. Marconi, I. Musella +3
The mid-infrared period-luminosity (P-L) relation for Cepheids will be important in the JWST era, as it holds the promise of deriving the Hubble constant within 2% accuracy. We pre…
A Spitzer IRAC Imaging Survey for T Dwarf Companions Around M, L, and T Dwarfs: Observations, Results, and Monte Carlo Population Analyses
Joseph Carson, Massimo Marengo, Brian Patten +8
We report observational techniques, results, and Monte Carlo population analyses from a Spitzer Infrared Array Camera imaging survey for substellar companions to 117 nearby M, L, a…
SAGE-Spectroscopy: The life-cycle of dust and gas in the Large Magellanic Cloud. Data delivery document v3.0
Paul M. Woods, G. C. Sloan, Karl D. Gordon +3
The SAGE-Spectroscopy Spitzer legacy program (SAGE-Spec; PI: F. Kemper, PID: 40159; Kemper et al. 2010) is the IRS spectroscopic follow-up to the successful SAGE-LMC legacy program…
