New ExoMol line lists AloHa for AlH and AlD are presented improving theprevious line lists WYLLoT (Yurchenko et al., MNRAS 479, 1401 (2018)). Therevision is motivated by the recent experimental measurements and astrophysicalfindings involving the highly excited rotational states of AlH in its$A\,^{1}\Pi-{X}\,^{1}\Sigma^{+}$ system. A new high-resolution emissionspectrum of ten bands from the ${A}\,^{1}\Pi-{X}\,^{1}\Sigma^{+}$ system ofAlD, in the region $17300 - 32000$ cm$^{-1}$ was recorded with a Fouriertransform spectrometer, which probes the predissociative $A\,^1\Pi$ $v=2$state. The AlD new line positions are combined with all available experimentaldata on AlH and AlD to construct a comprehensive set of empirical rovibronicenergies of AlH and AlD covering the $X\,^1\Sigma^+$ and $A\,^1\Pi$ electronicstates using the MARVEL approach. We then refine the spectroscopic model WYLLoTto our experimentally derived energies using the nuclear-motion code Duo anduse this fit to produce improved line lists for $^{27}$AlH, $^{27}$AlD and$^{26}$AlH with a better coverage of the rotationally excited states of$A\,^1\Pi$ in the predissociative energy region. The lifetimes of thepredissociative states are estimated and are included in the line list usingthe new ExoMol data structure, alongside the temperature-dependent continuumcontribution to the photo-absorption spectra of AlH. The new line lists areshown to reproduce the experimental spectra of both AlH and AlD well, and todescribe the AlH absorption in the recently reported Proxima Cen spectrum,including the strong predissociative line broadening. The line lists areincluded into the ExoMol database www.exomol.com.
