Constraints on the Progenitor of SN 2010jl and Pre-Existing Hot Dust in its Surrounding Medium [PDF]

, 2017
A search for the progenitor of SN~2010jl, an unusually luminous core-collapse supernova of Type~IIn, using pre-explosion {\it Hubble}/WFPC2 and {\it Spitzer}/IRAC images of the region, yielded upper limits on the UV and near-infrared (IR) fluxes from any

Research of influence factors on characteristic parameters of coal dust explosio

Gong-kuang zidonghua, 2014
Influence of particle size, concentration and ignition energy of coal dust on the maximum pressure and its rising rate of coal dust explosion were researched by use of 20 L spherical explosion equipment. The research results show that under the condition

Disappearance of the Progenitor of Supernova iPTF13bvn [PDF]

, 2016
Supernova (SN) iPTF13bvn in NGC 5806 was the first Type Ib SN to have been tentatively associated with a progenitor candidate in pre-explosion images. We performed deep ultraviolet (UV) and optical Hubble Space Telescope (HST) observations of the SN site

Evidence for Pre-Existing Dust in the Bright Type IIn SN 2010jl [PDF]

, 2011
SN 2010jl was an extremely bright, Type IIn SNe which showed a significant IR excess no later than 90 days after explosion. We have obtained Spitzer 3.6 and 4.5 \mum and JHK observations of SN 2010jl \sim90 days post explosion.

New evidence on the origin of the microquasar GRO J1655-40 [PDF]

, 2007
Aims. Motivated by the new determination of the distance to the microquasar GRO J1655-40 by Foellmi et al. (2006), we conduct a detailed study of the distribution of the atomic and molecular gas, and dust around the open cluster NGC 6242, the possible ...
