text: 'We present volume-limited samples of cataclysmic variables (CVs) and AM CVn
binaries jointly selected from SRG/eROSITA eRASS1 and Gaia DR3 using an X-ray
+ optical color–color diagram (the "X-ray Main Sequence"). This tool identifies
all CV subtypes, including magnetic and low-accretion rate systems, in contrast
to most previous surveys. We find 23 CVs, 3 of which are AM CVns, out to 150 pc
in the Western Galactic Hemisphere. Our 150 pc sample is spectroscopically verified
and complete down to LX = 1.3 × 1029 erg s−1 in the 0.2–2.3 keV band, and we also
present CV candidates out to 300 pc and 1000 pc. We discovered two previously
unknown systems in our 150 pc sample: the third nearest AM CVn and a magnetic
period bouncer. We find the mean LX of CVs to be 〈LX〉 ≈ 4.6 × 1030 erg s−1, in
contrast to previous surveys which yielded 〈LX〉 ∼ 1031−1032 erg s−1. We construct
X-ray luminosity functions that, for the first time, flatten out at LX ∼ 1030
erg s−1. We infer average number, mass, and luminosity densities of ρN,CV = (3.7
± 0.7) × 10−6pc−3, (math formular), and (math formular), respectively, in the
solar neighborhood. Our uniform selection method also allows us to place meaningful
estimates on the space density of AM CVns, ρN,AM CVn = (5.5 ± 3.7) × 10−7 pc−3.
Magnetic CVs and period bouncers make up 35% and 25% of our sample, respectively.
This work, through a novel discovery technique, shows that the observed number
densities of CVs and AM CVns, as well as the fraction of period bouncers, are
still in tension with population synthesis estimates.'

text: 'A complete understanding of the central stars of planetary nebulae (CSPNe)
remains elusive. Over the past several decades, time-series photometry of CSPNe
has yielded significant results including, but not limited to, discoveries of
nearly 100 binary systems, insights into pulsations and winds in young white dwarfs,
and studies of stars undergoing very late thermal pulses. We have undertaken a
systematic study of optical photometric variability of cataloged CSPNe, using
the light curves from the Zwicky Transient Facility (ZTF). By applying appropriate
variability metrics, we arrive at a list of 94 highly variable CSPN candidates.
Based on the timescales of the light-curve activity, we classify the variables
broadly into short- and long-timescale variables. In this first paper in this
series, we focus on the former, which is the majority class comprising 83 objects.
We report periods for six sources for the first time, and recover several known
periodic variables. Among the aperiodic sources, most exhibit a jitter around
a median flux with a stable amplitude, and a few show outbursts. We draw attention
to WeSb 1, which shows a different kind of variability: prominent deep and aperiodic
dips, resembling transits from a dust/debris disk. We find strong evidence for
a binary nature of WeSb 1 (possibly an F-type subgiant companion). The compactness
of the emission lines and inferred high electron densities make WeSb 1 a candidate
for either an EGB 6-type planetary nucleus, or a symbiotic system inside an evolved
planetary nebula, both of which are rare objects. To demonstrate further promise
with ZTF, we report three additional newly identified periodic sources that do
not appear in the list of highly variable sources. Finally, we also introduce
a two-dimensional metric space defined by the von Neumann statistics and Pearson
Skew and demonstrate its effectiveness in identifying unique variables of astrophysical
interest, like WeSb 1.'

text: "White dwarfs (WDs) are the most abundant compact objects, and recent surveys
have suggested that over a third of WDs in accreting binaries host a strong (B
\ ≳ 1 MG) magnetic field. However, the origin and evolution of WD magnetism remain
under debate. Two WD pulsars, AR Sco and J191213.72–441045.1 (J1912), have been
found, which are non-accreting binaries hosting rapidly spinning (1.97 minutes
and 5.30 minutes, respectively) magnetic WDs. The WD in AR Sco is slowing down
on a (math formular) yr timescale. It is believed they will eventually become
polars, accreting systems in which a magnetic WD (B ≈ 10−240 MG) accretes from
a Roche lobe-filling donor spinning in sync with the orbit (≳78 minutes). Here,
we present multiwavelength data and analysis of Gaia22ayj, which outbursted in
2022 March. We find that Gaia22ayj is a magnetic accreting WD that is rapidly
spinning down (math formular\r\n yr) like WD pulsars, but shows clear evidence
of accretion, like polars. Strong linear polarization (40%) is detected in Gaia22ayj;
such high levels have only been seen in the WD pulsar AR Sco and demonstrate the
WD is magnetic. High speed photometry reveals a 9.36 minutes period accompanying
a high amplitude (∼2 mag) modulation. We associate this with a WD spin or spin–orbit
beat period, not an orbital period as was previously suggested. Fast (60 s) optical
spectroscopy reveals a broad \"hump,\" reminiscent of cyclotron emission in polars,
between 4000 and 8000 Å. We find an X-ray luminosity of (math formular) in the
0.3–8 keV energy range, while two very large array radio campaigns resulted in
a non-detection with a Fr < 15.8 μJy 3σ upper limit. The shared properties of
both WD pulsars and polars suggest that Gaia22ayj is a missing link between the
two classes of magnetic WD binaries."

text: We measure the mass distribution of main-sequence (MS) companions to hot subdwarf
B stars (sdBs) in post-common envelope binaries (PCEBs). We carried out a spectroscopic
survey of 14 eclipsing systems ("HW Vir binaries") with orbital periods of 3.8
< Porb < 12 hr, resulting in a well-understood selection function and a near-complete
sample of HW Vir binaries with G < 16. We constrain companion masses from the
radial velocity curves of the sdB stars. The companion mass distribution peaks
at MMS ≈ 0.15 M⊙ and drops off at MMS > 0.2 M⊙, with only two systems hosting
companions above the fully convective limit. There is no correlation between Porb
and MMS within the sample. A similar drop-off in the companion mass distribution
of white dwarf (WD) + MS PCEBs has been attributed to disrupted magnetic braking
(MB) below the fully convective limit. We compare the sdB companion mass distribution
to predictions of binary evolution simulations with a range of MB laws. Because
sdBs have short lifetimes compared to WDs, explaining the lack of higher-mass
MS companions to sdBs with disrupted MB requires MB to be boosted by a factor
of 20–100 relative to MB laws inferred from the rotation evolution of single stars.
We speculate that such boosting may be a result of irradiation-driven enhancement
of the MS stars' winds. An alternative possibility is that common envelope evolution
favors low-mass companions in short-period orbits, but the existence of massive
WD companions to sdBs with similar periods disfavors this scenario.

text: Stars strongly impact their environment, and shape structures on all scales
throughout the universe, in a process known as "feedback." Due to the complexity
of both stellar evolution and the physics of larger astrophysical structures,
there remain many unanswered questions about how feedback operates and what we
can learn about stars by studying their imprint on the wider universe. In this
white paper, we summarize discussions from the Lorentz Center meeting "Bringing
Stellar Evolution and Feedback Together" in 2022 April and identify key areas
where further dialog can bring about radical changes in how we view the relationship
between stars and the universe they live in.
