DESCUBRIMIENTO / DESCUBREN A UNOS 300 AÑOS LUZ

By admin
Por primera vez, dos exoplanetas orbitando una estrella similar al Sol. Se trata de un Sistema Solar que se encuentra en una etapa más temprana de evolución que el nuestro ...


El Observatorio Europeo Austral obtuvo la primera imagen de una estrella de tamaño semejante al Sol que se ubica a unos 300 años luz y es orbitada por dos planetas, informa la web de esa organización.
Las imágenes de sistemas solares con múltiples exoplanetas son extremadamente raras. En estrellas similares al Sol, los astrónomos no habían observado directamente más de un planeta en órbita.
Captada por el VLT –un grupo de cuatro telescopios ubicados en el cerro Paranal, en el norte de Chile–, la imagen ahora obtenida muestra la estrella TYC 8998-760-1 y dos gigantes gaseosos, a la manera de Júpiter o Saturno, pero más pesados.

El planeta interior tiene 14 veces la masa de Júpiter, y el exterior, seis veces. Están alejados de su estrella a distancias que equivalen a 160 y 320 veces la que media entre el Sol y la Tierra, respectivamente.

La estrella, ubicada en la constelación Mosca del hemisferio sur, tiene 17 millones de años de edad, lo que la hace una "versión muy joven de nuestro Sol", según la describió Alexander Bohn, estudiante de doctorado de la Universidad de Leiden (Países Bajos) y líder de la investigación.

Reversing C++ String And QString

By admin
After the rust string overview of its internal substructures, let's see if c++ QString storage is more light, but first we'r going to take a look to the c++ standard string object: At first sight we can see the allocation and deallocation created by the clang++ compiler, and the DAT_00400d34 is the string. If we use same algorithm than the rust code but in c++: We have a different decompilation layout. Note that the Ghidra scans very fast the c++ binaries, and with  rust binaries gets crazy for a while. Locating main is also very simple in a c++ compiled binary, indeed is more  low-level than rust. The byte array is initialized with a simply move instruction:         00400c4b 48 b8 68        MOV        RAX,0x6f77206f6c6c6568 And basic_string generates the string, in the case of  rust this was carazy endless set of calls, detected by ghidra as a runtime, but nevertheless the basic_str...
