We conducted one-dimensional stellar evolutionary numerical simulations to build blue supergiant models with a very low-envelope mass and super-Eddington luminosity of 10^7Lo that mimic the last phase common envelope evolution (CEE) where neutron star (NS) accretes from launches jets power system. Common supernovae (CEJSNe) are CEE transient events NS spirals-in inside then core red (RSG) event...

Abstract We have combined resolved stellar photometry from Hubble Space Telescope (HST), Spitzer, and Gaia to identify red supergiant (RSG) candidates in NGC 6946, based on their colors, proper motions, visual morphologies, spectral energy distributions. start with a large sample of 17,865 RSG solely HST near-infrared photometry. then chose small 385 these Spitzer matches for more detailed stud...

Equine herpesvirus type 1 (EHV-1) causes respiratory disease, abortion and neurological disorders in horses. Besides epithelial cells, CD172a+ monocytic cells become infected with EHV-1 in the respiratory mucosa and transport the virus from the apical side of the epithelium to the lamina propria en route to the lymph and blood circulation. Whether CD172a+ monocytic cells are specifically recrui...

Abstract We present preexplosion optical and infrared (IR) imaging at the site of type II supernova (SN II) 2023ixf in Messier 101 6.9 Mpc. astrometrically registered a ground-based image SN to archival Hubble Space Telescope (HST), Spitzer (Spitzer), near-IR images. A single point source is detected position consistent with wavelengths ranging from HST R band 4.5 μ m. Fitting blackbody red sup...
