The objective is to promote the consolidation of the professional careers of national and foreign researchers, so that they can develop their professional careers within SECTI.

Promoting the consolidation of the professional career of research personnel, encouraging the creation of permanent positions in the affiliated institutions and facilitating the start or strengthening of a line of research through the financing of their own R&D+ project. i, as well as the adaptation and renovation of spaces and laboratories and the improvement of the equipment necessary for its execution.

Within the general objective of promoting the consolidation of the professional career of researchers in any thematic area, this call specifically promotes the consolidation of people whose field of research is framed in a strategic theme related to either Artificial Intelligence (AI), or microelectronics and semiconductors (Chips), areas for which an additional budget will be allocated.

The financeable activities included in the actions are:

a) The incentive for the creation of a permanent position in the area of ​​knowledge of the main researcher of the action, if applicable.

b) The execution of one's own R&D&i project led by the main researcher of the action.

c) The adaptation of spaces, renovation of laboratories and improvement of equipment, necessary for the beginning or strengthening of the line of research of the main researcher of the action.

According to the classic textbook definition, planetary nebulae are bright bubbles of gas and dust ejected by individual low/intermediate mass stars as they reach the end of their lives and evolve into the white dwarf phase. However, there is increasing evidence that a significant fraction of planetary nebulae are the result of interactions between binary stars. The minimum fraction derived by observational studies in search of central post-common-envelope binaries is 20% (although some claim that it can be as high as 80% if we include all types of binaries). It is, therefore, so high that it raises questions about the accepted hypothesis, which tells us that all low-mass stars will end up forming a planetary nebula (since the binary fraction and distribution of orbital periods observed in the main sequence would imply that the post-common-envelope fraction was not greater than 5%).

Overall, there are many phenomena observed in evolved stars (for example, the formation of H-deficient white dwarfs) that can be attributed to the impact of interactions with a companion, but the viability of that hypothesis is difficult to assess with such reduced statistics. This proposal attempts to solve this problem by investigating the impact of binarity throughout the late phases of stellar evolution, starting with planetary nebulae and reaching the early part of the white dwarf cooling sequence. For planetary nebulae, the statistical analysis will be based on the compilation - and updated modeling using the most cutting-edge techniques - of data from the literature in combination with new high-quality data that come from mappers such as Kepler, TESS and Gaia. The analysis of the next phases depends on data coming from two observational programs that recently obtained allocated time with GTC-OSIRIS (60 hours in total), in addition to data from the Hubble Space Telescope Cycle 30 ``treasure'' program ( HST), of which the project IP is one of the co-Is. The final objective of this project is to integrate the results achieved for different phases of evolution of pre-white dwarfs and white dwarfs and provide a global knowledge of the impact of binarity in the last stages of the lives of low-massive stars.
