1 Evolved Super Star Clusters in M82
We present high-resolution optical and near-infrared HST observations of two adjacent regions in the fossil star-burst region in M82, B1 and B2. Age estimates date the cluster population in the fossil star-burst between ∼ 2 × 10 8 and ∼ 10 × 10 9 years, assuming solar metallicity. The star cluster population in B2 is more heavily affected by internal extinction than that in B1. Although our clu...
متن کاملA Sonification of Kepler Space Telescope Star Data
A performing artist group interested in including a sonification of star data from NASA’s Kepler space telescope in their next album release approached the Georgia Tech Sonification Lab for assistance in the process. The artists had few constraints for the authors other than wanting the end product to be true to the data, and a musically appealing “heavenly” sound. Several sonifications of the ...
متن کاملSuzaku Detection of an Intense X-Ray Flare from an A-Type Star, HD 161084
We report on a serendipitous detection of an intense X-ray flare from the Tycho reference source on HD 161084 during a Suzaku observation of the galactic center region for 20 ks. The X-ray Imaging Spectrometer recorded a flare from this A1-type dwarf or subgiant star with a flux of 1.4 10 12 erg s 1 cm 2 (0.5–10 keV) and a decay time scale of 0.5 hr. The spectrum is hard with a prominent Fe XXV...
متن کاملHAT-P-7b: AN EXTREMELY HOT MASSIVE PLANET TRANSITING A BRIGHT STAR IN THE KEPLER FIELD
We report on the latest discovery of the HATNet project; a very hot giant planet orbiting a bright (V = 10.5) star with a small semi-major axis of a = 0.0377± 0.0005AU. Ephemeris for the system is P = 2.2047299 ± 0.0000040 days, mid-transit time E = 2, 453, 790.2593 ± 0.0010 (BJD). Based on the available spectroscopic data on the host star and photometry of the system, the planet has a mass of ...
متن کاملNeutron star glitches have a substantial minimum size
Glitches are sudden spin-up events that punctuate the steady spin-down of pulsars and are thought to be due to the presence of a superfluid component within neutron stars. The precise glitch mechanism and its trigger, however, remain unknown. The size of glitches is a key diagnostic for models of the underlying physics. While the largest glitches have long been taken into account by theoretical...
