The search for dark matter (DM) is one of the most active and challenging areas of current research. Possible DM candidates are ultralight fields such as axions and weak interacting massive particles (WIMPs). Axions piled up in the center of stars are supposed to generate matter/DM configurations with oscillating geometries at a very rapid frequency, which is a multiple of the axion mass m B [Brito et al. (2015); Brito et al. (2016)]. Borra and Trottier (2016) recently found peculiar ultrafast periodic spectral modulations in 236 main sequence stars in the sample of 2.5 million spectra of galactic halo stars of the Sloan Digital Sky Survey (∼ 1% of main sequence stars in the F-K spectral range) that were interpreted as optical signals from extraterrestrial civilizations, suggesting them as possible candidates for the search for extraterrestrial intelligence (SETI) program. We argue, instead, that this could be the first indirect evidence of bosonic axion-like DM fields inside main sequence stars, with a stable radiative nucleus, where a stable DM core can be hosted. These oscillations were not observed in earlier stellar spectral classes probably because of the impossibility of starting a stable oscillatory regime due to the presence of chaotic motions in their convective nuclei. The axion mass values, (50 < m B < 2.4 × 10 3 ) µeV, obtained from the frequency range observed by Borra and Trottier, (0.6070 < f < 0.6077) THz, agree with the recent theoretical results from high-temperature lattice quantum chromodynamics [Borsanyi et al. (2016); Borsanyi et al. (2016b)]. PACS numbers:

“…For ALPs, we see that the newly derived direct detection bounds from XENON100 and CDMSlite partially improve on published bounds from CoGeNT, CDMS, XENON100, EDELWEISS, and KIMS [19][20][21][22][23]. However, we see that these are weaker than stellar cooling bounds [35,68,[78][79][80][81][82].…”

“…We find that existing constraints from XENON10, XENON100, and CDMSlite are weaker than the stellar cooling constraints [68,[78][79][80]. We checked that data from KIMS [23], in the absence of a background model, provides a weaker bound (not shown) than CDMSlite. However, the future SuperCDMS, as well as possible scintillating target experiments, can significantly improve on existing bounds for A masses below ∼ 10 eV.…”

“…The case of absorption in bound electrons, known as the axioelectric effect, has been originally suggested in [17,18]. Numerous direct-detection experiments have conducted searches assuming that the ALP constitutes the galactic DM or is produced in the Sun, including CoGeNT [19], CDMS [20], EDEL-WEISS [21], XENON100 [22], and KIMS [23]. Here we show that other existing data can improve on these bounds and provide projections for future experiments.…”

We consider the absorption by bound electrons of dark matter in the form of dark photons and axion-like particles, as well as of dark photons from the Sun, in current and next-generation direct detection experiments. Experiments sensitive to electron recoils can detect such particles with masses between a few eV to more than 10 keV. For dark photon dark matter, we update a previous bound based on XENON10 data and derive new bounds based on data from XENON100 and CDMSlite. We find these experiments to disfavor previously allowed parameter space. Moreover, we derive sensitivity projections for SuperCDMS at SNOLAB for silicon and germanium targets, as well as for various possible experiments with scintillating targets (cesium iodide, sodium iodide, and gallium arsenide). The projected sensitivity can probe large new regions of parameter space. For axionlike particles, the same current direction detection data improves on previously known direct-detection constraints but does not bound new parameter space beyond known stellar cooling bounds. However, projected sensitivities of the upcoming SuperCDMS SNOLAB using germanium can go beyond these and even probe parameter space consistent with possible hints from the white dwarf luminosity function. We find similar results for dark photons from the sun. For all cases, direct-detection experiments can have unprecedented sensitivity to dark-sector particles.

“…There is no excess of events that could be attributed to solar axion interactions and this translates into an axion-electron coupling limit g ae < 1.70 × 10 −11 Figure 8: (Color online) The observed 90% CL exclusion limits (red line) on the axion-electron coupling (g ae ) for the first 59.5 days data of COSINE-100 are shown together with the 68% and 95% probability bands for the expected 90% CL limit assuming the backgroundonly hypothesis. The limits are compared with the results set by XMASS [41], EDELWEISS-III [42], KIMS [43], XENON100 [44], PandaX-II [45], and LUX [46] experiments together with indirect astrophysical bounds of solar neutrino [47]. The inclined lines show two benchmark models of the DFSZ (cos 2 β = 1) and KSVZ. for axion masses in the 0-1 keV/c 2 range.…”

We present results from a search for solar axions with the COSINE-100 experiment. We find no evidence of solar axion events from a data-set of 6,303.9 kg·days exposure and set a 90 % confidence level upper limit on the axionelectron coupling, g ae , of 1.70 × 10 −11 for an axion mass less than 1 keV/c 2 . This limit excludes QCD axions heavier than 0.59 eV/c 2 in the DFSZ model and 168.1 eV/c 2 in the KSVZ model.
