Hard X-ray Emission Associated with White Dwarfs. IV. Signs of Accretion from Sub-stellar Companions

You-Hua Chu, Jesus A. Toala, Martin A. Guerrero +3

KPD 0005+5106, with an effective temperature of 200,000 K, is one of the hottest white dwarfs (WDs). ROSAT unexpectedly detected "hard" (1 keV) X-rays from this appar…

Spitzer 24 um Survey for Dust Disks around Hot White Dwarfs

You-Hua Chu, Kate Y. L. Su, Jana Bilikova +6

Two types of dust disks around white dwarfs (WDs) have been reported: small dust disks around cool metal-rich WDs consisting of tidally disrupted asteroids, and a large dust disk a…

Spitzer Surveys of Infrared Excesses of White Dwarfs

Y. -H. Chu, R. A. Gruendl, J. Bilíkovà +2

IR excesses of white dwarfs (WDs) can be used to diagnose the presence of low-mass companions, planets, and circumstellar dust. Using different combinations of wavelengths and WD t…

Spitzer 24 um Images of Planetary Nebulae

Y. -H. Chu, R. A. Gruendl, M. A. Guerrero +9

Spitzer MIPS 24 um images were obtained for 36 Galactic planetary nebulae (PNe) whose central stars are hot white dwarfs (WDs) or pre-WDs with effective temperatures of ~100,000 K…

Supernova Remnants in the Large Magellanic Clouds IX: Multiwavelength Analysis of the Physical Structure of N49

J. Bilikova, R. N. M. Williams, Y. -H. Chu +2

We present a multiwavelength analysis of the supernova remnant N49 in the Large Magellanic Cloud. Using high-resolution Hubble Space Telescope WFPC2 images of H-alpha, [S II] and […
