Fr 2-30 = PN? G126.8−15.5 is a faint emission nebula, hosting a 14th-mag central star that we identify here for the first time. Deep Hα and [O iii] images reveal a roughly elliptical nebula with dimensions of at least 22′ × 14′, fading into a surrounding network of even fainter emission. Optical spectrograms of the central star show it to have a subdwarf O spectral type, with a Gaia parallax distance of 890 pc. A model-atmosphere analysis gives parameters of Teff = 60 000 K, log g = 6.0, and a low helium content of nHe/nH = 0.0017. The location of the central star in the log g − log Teff plane is inconsistent with a post-asymptotic-giant-branch evolutionary status. Two alternatives are that it is a helium-burning post-extreme-horizontal-branch object, or a hydrogen-burning post-red-giant-branch star. In either case the evolutionary ages are so long that a detectable planetary nebula (PN) should not be present. We find evidence for a variable radial velocity (RV), suggesting that the star is a close binary. However, there are no photometric variations, and the spectral-energy distribution rules out a companion earlier than M2 V. The RVs of the star and surrounding nebula are discordant, and the nebula lacks typical PN morphology. We suggest that Fr 2–30 is a ‘PN mimic’ – the result of a chance encounter between the hot sdO star and an interstellar cloud. However, we note the puzzling fact that there are several nuclei of genuine PNe that are known to be in evolutionary states similar to that of the Fr 2-30 central star.

While the majority of lesbian, gay, bisexual and transgender (LGBT) adolescents, much like their cis-gendered heterosexual peers, will be confident and healthy young individuals, there are well-known health disparities, particularly within the transgendered community, which may lead to inferior health outcomes. To improve these outcomes, we must empower professionals to feel confident in their interactions with transgender adolescents so they can recognise, discuss and address these disparities. For many healthcare professionals, this may be a novel experience, but following the announcement in 2022 that the Gender Identity Development Service (GIDS) will move towards a regional model, these discussions increasingly frequently be encountered in a general paediatric setting. In this article, we discuss some of the topics which may be relevant to transgender young people during a general paediatric consultation.
