For the isotropic interior case, we consider a thin spherical shell characterized by an equation of state whose pressure is proportional to its mass density, enclosing a de Sitter spacetime and surrounded by Vaidya exterior spacetime. Our analysis reveals that stable gravastars can form under specific scenarios of radiative mechanisms for certain thin shell matter types. In addition, we briefly discuss the possibility of the existence of stable radiating anti-de Sitter gravastar formation. For the anisotropic interior, we use an anisotropic dark energy model with a Tolman–Matese–Whitman (TMW) mass function. We explore several thin shell matter types: standard, dark energy, and repulsive phantom. Our findings indicate that stable gravastars can emerge in this context, particularly with standard and repulsive phantom thin shells. Furthermore, our results suggest that the density of black holes is consistently higher than that of gravastars and normal stars, regardless of the type of matter in the thin shell. This observation supports the notion that gravastars and black holes are distinct entities, reinforcing the theoretical distinction between these two types of compact objects.</div></div>","PeriodicalId":8249,"journal":{"name":"Annals of Physics","volume":"476 ","pages":"Article 169965"},"PeriodicalIF":3.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143512656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This suggests that these factors significantly affect the location of the horizon. Furthermore, the black hole’s mass is critical; wormholes with larger masses are more stable, whereas wormholes with smaller masses have smaller stability zones. As the equation of state parameter varies across multiple values, more research reveals the effect of diverse matter compositions on the stability of nonrotating thin-shell wormholes.

We calculate the ground-state energy per particle at zero and low temperature for three- two- and one-dimensional two-component bosonic gases. By tuning the nonuniversal contribution to the interactions we address and establish conditions under which the formation and stability of a self-bound liquidlike phase or droplet with nonuniversal corrections to the interactions (DNUC) is favorable. At zero temperature in three-dimensions and considering the nonuniversal corrections to the attractive interactions as a fitting parameter the energy per particle for DNUC is in good agreement with some diffusion Monte Carlo results. In two dimensions the DNUC present small deviations regarding conventional droplets. For the one-dimensional DNUC the handling of the nonuniversal effects to the interactions achieves a qualitative agreement with the trend of some available Monte Carlo data in usual droplets. We also introduce some improved Gross–Pitaevskii equations to describe self-trapped DNUC in three, two and one dimension. We briefly discuss some aspects at low temperature regarding nonuniversal corrections to the interactions in Bose-Bose gases. We derive the dependencies on the nonuniversal contribution to the interactions but also on the difference between intra- and inter-species coupling constants. This last dependence crucially affect the three- and the two-dimensional DNUC driving thus to a thermal-induced instability. This thermal instability is also present in one-dimensional Bose-Bose gases, but it is not relevant on the formation of DNUC. This is explained because the necessary attraction mechanism to achieve this phase naturally arises in the fluctuations at zero temperature without major restrictions as it happens in the other dimensions.</div></div>","PeriodicalId":8249,"journal":{"name":"Annals of Physics","volume":"475 ","pages":"Article 169955"},"PeriodicalIF":3.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
