Dusty Debris around Solar-Type Stars: Temporal Disk Evolution

By C. Spangler, A. Sargent, M. Silverstone, E. Becklin, B. Zuckerman. 2001

152 citations recorded by the source corpus.

Using ISO-ISOPHOT, we carried out a survey of almost 150 stars to search for evidence of emission from dust orbiting young main-sequence stars, both in clusters and isolated systems. Over half of the detections are new examples of dusty stellar systems and demonstrate that such dust can be detected around numerous stars older than a few times 106 yr. Fluxes at 60 and either 90 or 100 μm for the new excess sources together with improved fluxes for a number of IRAS-identified sources are presented. Analysis of the excess luminosity relative to the stellar photosphere shows a systematic decline of this excess with stellar age consistent with a power-law index of -2.

• Transience of Hot Dust around Sun-like Stars (2006, background): “This is in broad agreement with the observed properties of debris disks: the mean dust luminosity at a given age falls off ∝ t−1.8 (Spangler et al. 2001); the mass inferred from detection statistics falls off ∝ t−0.5 (Greaves & Wyatt 2003), while the mass of the detected disks falls off ∝ t−1…”
